1. GENERAL DESCRIPTION 1. GENERAL DESCRIPTIONINTENSIA CRT-D 174 is an implantable cardioverter defibrillator for the recognition and treatment of ventricular tachycardia and fibrillation, with ventricular resynchronization, in patients with spontaneous or inducible tachyarrhythmias. INTENSIA CRT-D 174 is equipped with an accelerometer to allow adaptation of pacing to suit the patient’s activity. INTENSIA CRT-D 174 is also equipped with the RF wireless technology which enables to remotely monitor the patients who have the Sorin SMARTVIEW Monitor installed at home.INTENSIA CRT-D 174 provides high energy shocks (42 J) for enhanced safety, as well as automatic lead measurements to monitor system integrity.INTENSIA CRT-D 174 is protected against high-frequency signals emitted by cellular telephones.SORIN – INTENSIA CRT-D 174 – U151A 5
2. INDICATIONS 2. INDICATIONSINTENSIA CRT-D 174 is indicated for ventricular antitachycardia pacing and ventricular defibrillation for automated treatment of life threatening arrhythmias.The device is also indicated for the reduction of heart failure symptoms in medically optimized NYHA Functional Class III and IV patients with left ventricular ejection fraction of 35% or less, and a QRS duration of 150 ms or longer.6SORIN – INTENSIA CRT-D 174 – U151A
3. CONTRAINDICATIONS 3. CONTRAINDICATIONSImplantation of INTENSIA CRT-D 174 is contraindicated in patients:─whose ventricular tachyarrhythmias may have transient or reversible causes such as: acute myocardial infarction, digitalis intoxication, drowning, electrocution, electrolyte imbalance, hypoxia, sepsis, or unstable ischemic episodes,─who present incessant tachyarrhythmia,─who have an internal pacemaker,─whose primary disorder is bradyarrhythmias, or atrial tachyarrhythmias.Dual-chamber and single chamber atrial pacing is contraindicated in patients with chronic refractory atrial tachyarrhythmias.SORIN – INTENSIA CRT-D 174 – U151A 7
4. WARNINGS AND PRECAUTIONS 4. WARNINGS AND PRECAUTIONSThe patient should be warned of the potential risks of defibrillator malfunction if he is exposed to external magnetic, electrical, or electromagnetic signals.These potential interference sources may cause conversion to inhibited mode (because of noise detection), erratic delivery of VT or VF therapies, nominal programming, or much more rarely, irreversible damage to the device’s circuits.The main sources of high magnitude electromagnetic interference (EMI) are: powerful radiofrequency equipment (radar), industrial motors and transformers, induction furnaces, resistance, arc-welding equipment and high power loudspeakers.Be aware that the changes in the patient’s condition, drug regimen, and other factors may change the defibrillation threshold (DFT) which may result in non-conversion of the arrhythmia post-operatively. Successful conversion of ventricular fibrillation or ventricular tachycardia during arrhythmia conversion testing is no assurance that conversion will occur post-operatively.Resuscitation Availability:Do not perform device testing unless an external defibrillator and medical personnel skilled in cardiopulmonary resuscitation (CPR) are readily available.Electrical Isolation:Do not permit the patient to contact grounded equipment that could produce hazardous leakage current. Ensuing arrhythmia induction could result in the patient’s death.Disable the ICD During Handling:Program Shock Therapy to OFF during surgical implant and explant or post mortem procedures. The device can deliver a serious high energy shock should accidental contact be made with the defibrillation electrodes.Antitheft gates:Since antitheft devices at the entrance to stores are not subject to any safety standards, it is advisable to spend as little time as possible in their vicinity.Airport detection systems:Since airport detection systems are not subject to any safety standards, it is advisable to spend as little time as possible in their vicinity.High voltage power transmission lines:High voltage power transmission lines may generate enough EMI to interfere with defibrillator operation if approached too closely.Communication equipment:Communication equipment such as microwave transmitters, linear power amplifiers, or high-power amateur transmitters may generate enough EMI to interfere with defibrillator operation if approached too closely.Home appliances:Home appliances that are in good working order and properly grounded do not usually produce enough EMI to interfere with defibrillator operation. There are reports of device 8SORIN – INTENSIA CRT-D 174 – U151A
4. WARNINGS AND PRECAUTIONSdisturbances caused by electric hand tools or electric razors used directly over the device implant site.4.1. RISKS RELATED TO MEDICAL ENVIRONMENTIt is advisable to carefully monitor defibrillator operation prior to and after any medical treatment during which an electrical current from an external source passes through the patient's body.Magnetic Resonance Imaging:MRI is strictly contraindicated in cardiac defibrillator patients.Radiofrequency ablation:A radiofrequency ablation procedure in a patient with a generator may cause device malfunction or damage. RF ablation risks may be minimized by:1. Programming Shock Therapy and ATP to OFF.2. Avoiding direct contact between the ablation catheter and the implanted lead or generator.3. Positioning the ground, placing it so that the current pathway does not pass through or near the device, i.e. place the ground plate under the patient’s buttocks or legs.4. Having external defibrillation equipment available.Electrocautery or diathermy device:Diathermy and electrocautery equipment should not be used. If such devices must be used:1. Keep the current path and ground plate as far away from the device and the leads as possible (a minimum of 15 cm [six inches]).2. Before procedure, disable ATP and shock therapies.3. During the procedure, keep the electrocautery device as far as possible from the cardiac defibrillator. Set it at minimum intensity. Use it briefly.4. After the procedure, check for proper implant function. The device should never be exposed directly to the diathermy source.External defibrillation:INTENSIA CRT-D 174 is protected from external defibrillation shocks.1. Before external defibrillation, disable ATP and shock therapies.2. During external defibrillation, it is advisable to avoid placing the defibrillating paddles directly over the casing or over the leads. The defibrillating paddles should preferably be placed in an anteroposterior position.3. Avoid any direct contact between the defibrillation paddles and the conductive parts of the implanted leads or casing of the implanted device.4. After external defibrillation, check for proper device function.Radiation therapy:Avoid exposure to ionizing radiation. Betatrons are contraindicated. If high doses of radiation therapy cannot be avoided, the defibrillator should be protected from direct exposure with a SORIN – INTENSIA CRT-D 174 – U151A 9CAUTION: Do not tap sharply on the ICD can after implant, because the ICD's sensing circuits can detect this as P-waves or R-waves, and such oversensing could result in inappropriate pacing, inhibition, or therapy. Normal activities after implant do not result in such oversensing.
4. WARNINGS AND PRECAUTIONSprotection shield. ATP and shock therapies should be disabled during exposure and proper device function should be checked regularly afterwards. Resulting damage may not be immediately detectable. If irradiation of tissues close to the implantation site is necessary, it is recommended that the cardiac defibrillator be moved. As a safety measure, an external defibrillator should be immediately available.Lithotripsy:Lithotripsy may permanently damage the device if it is at the focal point of the lithotripsy beam. If lithotripsy must be used, keep the defibrillator at least 2.5 to 5 cm (1-2 inches) away from the focal point of the lithotripsy beam.Diagnostic ultrasound (echography):The defibrillator is not affected by ultrasound imaging devices.Scales with body fat monitors and electronic muscle stimulators:A patient with an implanted INTENSIA CRT-D 174 should not use these devices.4.2. STERILIZATION, STORAGE AND HANDLINGResterilization:Do not resterilize and re-implant explanted ICDs."Use Before" Date:A "Use Before" date is printed on the outer storage package and on the sterile package. Do not implant the device after this date because the battery may have reduced longevity and sterility may be affected. It should be returned to Sorin.If Package is damaged:Do not use the device or accessories if the packaging is wet, punctured, opened or damaged because the integrity of the sterile packaging may be compromised. Return the device to the manufacturer.Device Storage:Store the device in a clean area, away from magnets, kits containing magnets, and sources of electromagnetic interference to avoid device damage. Store the device between 0 - 50 °C (32 - 122 °F). Temperatures outside the specified range may damage the device.Equilibration:Allow the device to reach room temperature before programming or implanting the device because rapid temperature changes may affect initial device function.4.3. IMPLANTATION AND DEVICE PROGRAMMINGUse only a Sorin programmer to communicate with the device.Do not inadvertently position any magnet over the ICD; this suspends tachyarrhythmia detection and treatment.Replace the device when the RRT (Recommended Replacement Time*) point (defined by a battery voltage of 2.66 ± 0.01 V or a magnet rate lower than or equal to 80 bpm) is reached.Program device parameters such as sensitivity threshold and VT and VF detection intervals as specified in the device manuals.10 SORIN – INTENSIA CRT-D 174 – U151A
4. WARNINGS AND PRECAUTIONSLead System:Do not use a lead system other than those with demonstrated compatibility because undersensing cardiac activity and failure to deliver necessary therapy may result.In situations where an ICD and a pacemaker are implanted in the same patient, interaction testing should be completed. If the interaction between the ICD and the pacemaker cannot be resolved through repositioning of the leads or reprogramming of either the pacemaker or the ICD, the pacemaker should not be implanted (or should be explanted if previously implanted).Failure to properly insert the torque screwdriver into the perforation at an angle perpendicular to the connector receptacle may result in damage to the sealing system and its self-sealing properties.It is recommended that a security margin of at least 10 J be demonstrated between the effective shock energy and maximum programmable energy. Carefully confirm that true ventricular fibrillation has been induced because the DFT for ventricular tachycardia or flutter may be lower.The defibrillator should be implanted with the engraved side facing outwards in order to facilitate telemetric communication with the programming head and to display the radiographic identification correctly.*: corresponds to ERI (Elective Replacement Indicator) previously used. 4.4. LEAD EVALUATION AND LEAD CONNECTIONINTENSIA CRT-D 174 has two IS-1, and one DF-4 connector ports.IS-1 refers to the international standard whereby leads and generators from different manufacturers are assured a basic fit (ISO 5841-3:2013).DF-4 refers to the international standard for defibrillation lead connectors (ISO 27186:2010).Do not use the device with leads which have not been positively tested.Do not tie a ligature directly to the lead body, tie it too tightly, or otherwise create excessive strain at the insertion site as this may damage the lead. Use the lead stabilizer to secure the lead lateral to the venous entry site.Do not immerse the leads in mineral oil, silicone oil, or any other liquid.Do not grip the lead with surgical instruments.Do not use excessive force or surgical instruments to insert a stylet into a lead.Use ventricular transvenous leads with caution in patients with either a mechanical or bioprosthetic tricuspid valvular prosthesis.Use the correct suture sleeve (when needed) for each lead, to immobilize the lead and protect it against damage from ligatures.Never implant the system with a lead system that has a measured shock impedance of less than 30 ohms. A protection circuit in the defibrillator prevents shock delivery when impedance is too low. If the shock impedance is less than 30 ohms, reposition the lead system to allow a greater distance between the electrodes.Do not kink leads. Kinking leads may cause additional stress on the leads, possibly resulting in lead fracture.Do not insert a lead connector pin into the connector block without first visually verifying that the setscrews are sufficiently retracted. Do not tighten the setscrews unless a lead connector pin is inserted because it could damage the connector block.SORIN – INTENSIA CRT-D 174 – U151A 11
4. WARNINGS AND PRECAUTIONSLead electrodes in contact during a cardioversion or defibrillation therapy will cause current to bypass the heart, possibly damaging the ICD and the leads. While the ICD is connected to the leads, make sure that the metal portions of any electrodes do not touch each other.If a pacing lead is abandoned rather than removed, it must be capped to ensure that it is not a pathway for currents to or from the heart.If a thoracotomy is required to place epicardial patches, it should be done during a separate procedure to reduce the risk of morbidity and mortality.Do not place the patch lead over nerve tissue as this may cause nerve damage.Place the patch lead with the conducting coil side facing the heart to ensure delivery of energy to the heart.Place the sutures well outside the coil of the patch lead or in the area between the coils to avoid possible coil fracture.If countershock is unsuccessful using external paddles, adjust the external paddle position (e.g., anterior-lateral to anterior-posterior) and be sure that the external paddle is not positioned over the patch.Do not fold, alter, or remove any portion of the patch as it may compromise electrode function or longevity.If a header port is unused on the generator, the port must be plugged to protect the generator.4.5. GENERATOR EXPLANT AND DISPOSALInterrogate the device, and program shock therapy off prior to explanting, cleaning or shipping the device to prevent unwanted shocks.Return all explanted generators and leads to the manufacturer.Never incinerate the device due to the potential for explosion. The device must be explanted before cremation.12 SORIN – INTENSIA CRT-D 174 – U151A

6. CLINICAL STUDIES 6. CLINICAL STUDIESClinical data presented in this section are from the MSP clinical study. INTENSIA CRT-D 174 is similar in design and function to the ALTO 2 MSP and OVATIO CRT-D devices. The data provided are applicable to INTENSIA CRT-D 174.6.1. MSP CLINICAL STUDYOVATIO CRT-D and earlier models were evaluated clinically in an international, multi-center, randomized clinical trial of Sorin’s cardiac resynchronization therapy (CRT-D) system. Investigators attempted to implant study devices in 190 patients. A total of 182 patients received study devices and had an exposure of over 165 device years. Of those patients, 19 received OVATIO CRT-D, 160 received ALTO 2 MSP, and 3 received ALTO MSP.6.1.1 . ObjectivesThe primary objectives of the study were to demonstrate:─Greater improvement in a composite endpoint (percent improvement in peak VO2 percent improvement in quality of life) for CRT-D patients than for control patients.─System complication-free rate ≥ 67 % at six months.6.1.2 . MethodsPatients were New York Heart Association class III or IV and had one or more indications for an implantable cardioverter defibrillator (ICD). Patients performed cardiopulmonary exercise testing at baseline and six-months after randomization. Patients were implanted with a Sorin ICD with CRT-D, a Situs UW28D left ventricular lead, and commercially available right atrial and ventricular leads. Routine follow-ups were at pre-discharge, randomization (3-14 days post-implant), one month, three months, and six months post randomization.6.1.3 .

6. CLINICAL STUDIES6.1.5 . Clinical Results V-V timingV-V programmable settings were available for the clinical study devices as follows: ALTO MSP model 617 (not programmable for V-V delay), ALTO 2 MSP model 627 values (0, 31, 39, 47, 55 and 63 ms) and OVATIO CRT-D 6750 values (0 to 63 ms in steps of 8 ms).The graph below shows the programmed V-V settings at randomization by percentage of patients programmed to each combination of Synchronous BiV pacing and V-V delay.The optimization protocol in the clinical study specified that each patient randomized should undergo echo guided V-V optimization. Per the investigational plan for the MSP Clinical 18 SORIN – INTENSIA CRT-D 174 – U151A
6. CLINICAL STUDIESTrial, a uniform protocol was used for V-V programming. This protocol required all patients to undergo echo-guided V-V delay optimization before randomization (2 to 14 days post-implant). The optimal V-V delay was determined by finding the programmable V-V delay and ventricular chamber pacing order (RV then LV, or LV then RV) providing the maximum time velocity integral (TVI or VTI) across the left ventricular outflow tract (LVOT).Only those patients randomized to the Test arm were required to be programmed per the optimization protocol for the V-V delay.Of the 177 patients that presented at randomization, 3 had Model 617 which does not have V-V programmability hence the inability to optimize. Of the remaining 174 patients, 154 (89%) were tested per the V-V optimization protocol. One hundred forty-nine (149) of the 154 patients who were tested per the V-V optimization protocol were programmed per the recommended or randomized V-V delay (97%). Thirty-one (31) patients were programmed to BiV synchronous (V-V delay 0ms), 46 were programmed to Sequential BiV (LV then RV), 22 were programmed to Sequential (RV then LV), and the remaining 50 patients were randomized to RV only.A sub-analysis of the composite endpoint comparing the subset of CRT-D patients with optimized V-V delays vs. the subset of patients that did not undergo V-V delay optimization demonstrated similar results in both groups. The CRT-D patients who did not undergo V-V delay optimization showed a smaller improvement in the composite endpoint, although the sample size did not permit conclusions based on data from this subset.SORIN – INTENSIA CRT-D 174 – U151A 19
7. PATIENT SELECTION AND TREATMENT 7. PATIENT SELECTION AND TREATMENT7.1. INDIVIDUALIZATION OF TREATMENTExercise stress testing:If the patient’s condition permits, use exercise stress testing to:─Determine the maximum rate of the patient’s normal rhythm,─Identify any supraventricular tachyarrhythmias,─Identify exercise-induced tachyarrhythmias.The maximum exercise rate or the presence of supraventricular tachyarrhythmias may influence selection of programmable parameters. Holter monitoring or other extended ECG monitoring also may be helpful.Electrophysiologic (EP) testing:EP testing may be useful for ICD candidates.EP testing may identify the classifications and rates of all the ventricular and atrial arrhythmias, whether spontaneous or during EP testing.Drug resistant supraventricular tachyarrhythmias (SVTs):Drug resistant supraventricular tachyarrhythmias (SVTs) may initiate frequent unwanted device therapy.A careful choice of programming options is necessary for such patients.Antiarrhythmic drug therapy:If the patient is being treated with antiarrhythmic or cardiac drugs, the patient should be on a maintenance drug dose rather than a loading dose at the time of ICD implantation. If changes to drug therapy are made, repeated arrhythmia inductions are recommended to verify ICD detection and conversion. The ICD also may need to be reprogrammed.Changes in a patient’s antiarrhythmic drug or any other medication that affects the patient’s normal cardiac rate or conduction can affect the rate of tachyarrhythmias and/or efficacy of therapy.Direct any questions regarding the individualization of patient therapy to Sorin’s representative.20 SORIN – INTENSIA CRT-D 174 – U151ACAUTION: To avoid inappropriate therapy during an exercise stress test, do not reprogram any parameter during the test. When a parameter is reprogrammed, PARAD/PARAD+ algorithm forces acceleration to "ventricular". During conducted sinus tachycardia within the programmed Tachy zone, the device detects a 1:1 fast rhythm. Assuming that acceleration was set to ventricular by reprogramming, the device may identify this as a VT, and may immediately apply the corresponding therapy.

13. DEVICE DESCRIPTION 13. DEVICE DESCRIPTIONThe INTENSIA CRT-D system includes the model 174 ICD device and programming system. The programming system includes the Sorin dedicated programmer with the SMARTVIEW programming software connected to a CPR3 programming head. The programming system is configured and furnished by Sorin.The INTENSIA CRT-D 174 can serve as a defibrillation electrode (active housing) with a total surface area of 76 cm².The INTENSIA CRT-D 174 is designed to recognize and treat slow or fast VT and VF by continuously monitoring atrial and ventricular activity to identify persistent ventricular arrhythmias and to deliver appropriate therapies. INTENSIA CRT-D 174 features the PARAD/PARAD+ algorithm, which is specifically designed to differentiate ventricular tachycardias from fast rhythms of supraventricular origin. PARAD/PARAD+ continuously monitors R-R interval stability, searches for long cycles, assesses the degree of P-R association, evaluates sudden onset and determines the chamber of arrhythmia acceleration.In addition to the advanced detection scheme, INTENSIA CRT-D 174 offers programmable single, dual or triple-chamber pacing therapy (DDD, DDI, VVI or SafeR (AAI <> DDD) modes) with or without rate-responsive capabilities (DDDR, DDIR, VVIR, DDD/DDIR and SafeR-R (AAIR <> DDDR) modes) using an acceleration sensor. An automatic AV delay algorithm as well as a mode switching function are available.INTENSIA CRT-D 174 enables an adjustment of the interventricular delay, and provides the possibility of adapting pacing to each ventricle. The ICD is intended to resynchronize uncoordinated contraction of the heart by simultaneously or sequentially pacing both ventricles.INTENSIA CRT-D 174 offers tiered therapy. Therapies can be programmed independently in each zone:─in the Slow VT and VT zones: two ATP programs, up to two shocks with programmable energy and up to four shocks with maximum energy can be programmed;─in the VF zone: one ATP program, up to two shocks with programmable energy and up to four shocks with maximum energy can be programmed.The ATP can be applied in RV, LV or RV and LV pacing with a VV delay equal to 0 ms. ATP pacing configuration is independent of ventricular pacing configuration.When the rhythm changes from one zone to another, the device delivers the therapy programmed in this zone, starting with the same or more aggressive program for the area. The ATP program in the VF zone will only be applied if the VT coupling interval is longer than the programmed fast VT cycle length.The INTENSIA CRT-D 174 offers biphasic shocks with a maximum stored energy of 42 J. The shock configuration (electrodes used to apply the shock) can be chosen by programming one of the following combinations: can and one coil, can and two coils, two coils only.Other features are as follows:─Automatic ventricular sensitivity control─Non-committed shocks─Electrophysiological studies (EPS) with real-time markers or electrograms: 30 SORIN – INTENSIA CRT-D 174 – U151A
13. DEVICE DESCRIPTION─Programmer-controlled VT induction sequences,─Programmer-controlled VF inductions (30 Hz rapid pacing or shock on T),─Programmable electrogram vectors (EGM A, EGM V, RVcoil-CAN, SVC-CAN, RVcoil-SVC, LV bip, LV tip-RV),─Real-time annotations displayed with the markers and indicating the majority rhythm,─Manual ATP sequences,─Manual shocks.─Rescue shock─Follow-up tests: ─Pacing lead impedance,─Coil impedance,─Capacitor charge time,─Sensitivity test,─Pacing threshold tests.─Data storage: ─Therapy History Report,─Statistics (pace/sense, therapy, shocks, and battery voltage),─Up to 14 complete Holter records with event logs, marker channel notation, and electrogram records.The connector head has three ports:─Atrial “IS-1” port: performs atrial bipolar pace/sense,─LV “IS-1” port: performs left ventricular bipolar pace,─RV “DF-4” port: performs right ventricular bipolar pace/sense, port for RV/SVC defibrillation coils.Both pace/sense ports are compatible with the IS-1 standard and defibrillation ports is compatible with the DF-4 standard.Distal lead terminal connections are secured with set-screws accessed via self-sealing silicone plugs. All lead connections pass through the header into the device via feedthroughs.Programming System:The Sorin programmer is used in conjunction with specific programmer software to interrogate and program the implanted device at implant and during patient follow-up procedures.Remote Monitoring:INTENSIA CRT-D 174 is also equipped with the RF wireless technology which enables to remotely monitor the patients who have the Sorin SMARTVIEW Monitor installed at home.SORIN – INTENSIA CRT-D 174 – U151A 31
14. IMPLANT PROCEDURE 14. IMPLANT PROCEDURE14.1. NECESSARY EQUIPMENTImplantation of INTENSIA CRT-D 174 requires the following equipment:─Sorin dedicated programmer, equipped with the SMARTVIEW software interface and with the programming head,─pacing system analyzer, as well as its sterile connecting cables, to evaluate the pacing and sensing thresholds,─a complete set of leads with corresponding introducers,─physiological signal monitor capable of displaying simultaneously the surface ECG and arterial pressure,─an external defibrillator with sterile external paddles,─sterile cover for the telemetry head.14.2. PACKAGING14.2.1 . ContentsThe INTENSIA CRT-D 174 and its accessories are ethylene oxide sterilized and hermetically sealed in two-ply clear packaging meeting international requirements.The sterile packaging contains a defibrillator and one screwdriver.The non-sterile items contained in the outer storage package are the implant manual, the ICD Registration Form and its envelope, the patient booklet, the ICD ID card and 12 identification labels.Once delivered, INTENSIA CRT-D 174 is programmed to as-shipped values that are different from nominal values (see Chapter “Programmable Parameters” for details).14.3. OPTIONAL EQUIPMENTThe following equipment may be required during implantation of INTENSIA CRT-D 174:─an IS-1 insulating plug to close the atrial port─a DF-4/DF-1 adaptor in case of replacement and use of DF-1 lead─sterile water to clean traces of blood. Any parts cleaned with sterile water must be thoroughly dried.─mineral oil to lubricate if necessary─a lead cap to isolate a lead which is not used32 SORIN – INTENSIA CRT-D 174 – U151ANOTE: In case you’re implanting a DF-4 lead, please verify its compatibility with standard alligators pin; please refer to the lead user’s manual for more details.
14. IMPLANT PROCEDURE14.4. BEFORE OPENING THE PACKAGEBefore opening the package, check the "Use Before" date printed on the labels on the box and on the sterile package. Defibrillators that have not been implanted before that date should be returned to Sorin.Interrogate the device: ─if a warning is displayed, do not implant the device and contact your Sorin representative.─if magnet rate is lower than 91 min-1, and if the last reforming/charge occurred more than one week ago, do not implant the device. Otherwise wait for one more week before checking the magnet rate again. NOTE : The magnet rate and battery voltage can decrease before the expiration date is reached. However, the magnet rate should be equal to or higher than 91 min-1 at the time of implant.Devices MUST NOT be interrogated and programmed within the vicinity of other devices.Also check the integrity of the sterile package. The sterility of the contents is no longer guaranteed if the package has been pierced or altered. If the defibrillator is no longer sterile, it should be returned in its packaging to Sorin. Any re-sterilization of the unit is at the discretion of Sorin.14.5. PRIOR TO IMPLANTATIONUse the programmer to verify the defibrillator can be interrogated before implantation.Verify all shock therapies are disabled in order to avoid accidental discharge during implantation.It is not advisable to program the Smoothing function before implantation, since the defibrillator may detect noise and pace at a rate higher than the programmed basic rate.14.6. DEVICE PLACEMENTThe pocket should be prepared in the left pectoral position, either subcutaneously or submuscularly. Subcutaneous device implantation is recommended for optimal RF communication efficacy.Implantation in an abdominal position is not advisable.In its final position, the defibrillator should be no more than 4 cm below the skin surface.14.7. CHOOSING THE TYPE OF LEADThe defibrillator should be connected to:─one bipolar atrial sensing/pacing lead ─one quadripolar/tripolar right ventricular lead with bipolar sensing/pacing electrodes and one or two defibrillation coils─one unipolar or bipolar left ventricular pacing lead.The choice of leads and their configuration is left to the implanting physician’s judgment.SORIN – INTENSIA CRT-D 174 – U151A 33CAUTION: Do not shake or tap sharply on the ICD package with the ICD inside, because the ICD's sensing circuits can interpret this as P-waves or R-waves and record these as an arrhythmia episode. If unusual shaking or tapping of the package results in a stored arrhythmia episode, erase the recording before using the ICD.
14. IMPLANT PROCEDUREConnectors:The unipolar and bipolar pacing/sensing connectors are compatible with the IS-1 standard and the quadripolar connector is compatible with the DF-4 standard (refer to the “Lead evaluation and lead connection” sub-section in the “Warnings and precautions” section).14.8. SHOCK CONFIGURATION (+ -> -)The shock configuration is the energy pathway between the defibrillation electrodes. If an atrial coil is present, the shock configuration can be programmed for bi-directional shocks.Programming:When active case and SVC are both programmed to Yes, the shock configuration can be programmed to: ─RV to Case (or Case to RV),─or RV to SVC (or SVC to RV),─or RV to Case+SVC (or Case+SVC to RV). RV to Case+SVC RV to Case RV to SVCThe polarity of shock is determined by the parameter itself.14.9. MEASUREMENT OF THRESHOLDS AT IMPLANTPacing and sensing thresholds should be measured at implant.Pacing thresholds:Acute thresholds should be lower than 1 V (or 2 mA) for a 0.35 ms pulse width, in both ventricles and in the atrium.Sensing thresholds:For proper right ventricular sensing, the amplitude of the R-wave should be greater than 5 mV.34 SORIN – INTENSIA CRT-D 174 – U151ANOTE1: Please note that DF-1 standard compliant lead is not compatible with DF-4 connector. In the opposite, DF-4 standard compliant lead is not compatible with DF-1 connector. In case of defibrillator replacement and use of a DF-1 lead or any other lead type that require an adaptor for this device, please contact your Sorin representative for any information on lead / connector compatibility question.NOTE2: In case no atrial lead is implanted, the atrial port should be plugged with IS-1 insulating plug and a single chamber mode (VVI-VVIR) should be programmed. PARAD and PARAD+ should not be used.
14. IMPLANT PROCEDUREFor proper atrial sensing, the amplitude of the P-wave should be greater than 2 mV.Pacing impedance measurements:Right ventricular, left ventricular and atrial pacing impedances should range from 200 to 3000 ohms (refer to the lead characteristics, especially if high impedance leads are used).14.10. LEADS CONNECTIONImplant the ventricular leads, then the atrial lead.Each lead must be connected to the corresponding connector port. The position of each connector is indicated on the casing.Tighten only the distal inserts. To connect each lead, proceed as follows:1. Clean the lead terminal pins thoroughly, if necessary (device replacement).2. Lubricate the lead terminal pins with sterile water, if necessary.3. Do not insert a lead connector pin into the connector block without first visually verifying that the lead port is not filled with any obstacle.4. Insert the screwdriver into the pre-inserted screw socket of the appropriate port (in order to allow excess air to bleed out and to make the insertion of the lead pin easier).5. Insert the lead pin all the way into the port (check that the pin protrudes beyond the distal insert).6. Tighten, check the tightness and ensure the lead pin still protrudes beyond the distal insert, and did not move.1. Do not tighten the pre-inserted screws when there is no lead (this could damage the connector). 2. Do not loosen the screws before inserting the connector (subsequent risk of being unable to reinsert the screw).3. When mineral oil or sterile water is used to make lead insertion easier, the screwdriver should remain inserted into the pre-inserted screw socket when checking the tightness. As a matter of fact, when the lead port is filled with a liquid, the physics piston effect can give the feeling the lead is properly tightened. 4. One single set screw is located on the side of the connection header.5. Use only the screwdriver provided with the defibrillator. Maintain the screwdriver's shaft perpendicular to the plane of the defibrillator (see figure below).6. Removing the screwdriver: to avoid all risk of loosening screws during removal, hold the screwdriver by its metal part and not by the handle.SORIN – INTENSIA CRT-D 174 – U151A 35CAUTION: CAUTION:
14. IMPLANT PROCEDURETo ensure full insertion, push the screwdriver's hex tip smoothly into the setscrew until it reaches the bottom of the hex chamber in the screw, which could be felt as a solid metallic contact. Do not implant the defibrillator if there is no feeling of solid metallic contact. Do not implant the defibrillator if the wrench does not click when attempting to tighten the setscrew on the lead pin.In the case of an external defibrillation shock delivered to the patient, always check the programming and functioning of the device, in particular its capacity to deliver shocks.14.11. DEVICE IMPLANTATIONINTENSIA CRT-D 174 should be implanted with the engraved side facing outwards for optimal communication with the programming head and radiographic identification.Carefully wind excess lead and place in a separate pocket to the side of the defibrillator.It is recommended to not place any excess wire between the can and the heart.Suture the casing connector to the muscle using the hole provided for this purpose, in order to avoid potential migration of the device into the pectoral muscle.14.12. TESTS AND PROGRAMMINGDuring the implant testing procedure, it is recommended that a security margin of at least 10 J be demonstrated between the effective shock energy and maximum programmable energy.Enable shock therapies, then program the defibrillator.Verify that the defibrillation lead impedance for each shock delivered ranges from 30 to 150 ohms. Check the lead connection if the values are outside these boundaries.Save the programming data on the programmer’s hard disk and on an external storage device (if desired).36 SORIN – INTENSIA CRT-D 174 – U151AWARNING: Ensure that the screwdriver's tip is fully inserted in the setscrew; otherwise the screwdriver can damage the setscrew and prevent connection with or disconnection from the lead.NOTE: To optimize cardioversion/defibrillation shocks, electrodes must be positioned so that the electric field between anode(s) and cathode covers the largest myocardial mass. In normal conditions, the anode and cathode are adequately separated. In case of a short-circuit, the shock may be aborted to prevent damaging the defibrillator.
15. SPECIAL MODES 15. SPECIAL MODES15.1. SAFETY MODE (NOMINAL VALUES)Nominal values may be rapidly restored by pressing the following button on the programming head or programmer keyboard:or via the Emergency button on the SMARTVIEW screen.In safety mode, the defibrillator operates with the parameters underlined in the table of programmable parameters.15.2. MAGNET MODEWhen the magnet is applied:─antiarrhythmia functions are inhibited (detection of rhythm disturbances, charging, and therapy),─hysteresis, VV delay and AVD paced/sensed offset are set to 0,─pacing amplitude is set to 6 V,─pulse width is set to maximum,─pacing rate is set to the magnet rate,─the following functions are disabled: ventricular arrhythmia prevention, Mode Switch, Anti-PMT, Smoothing, Rate Response.When the magnet is removed:─the sensor rate is forced to the basic rate,─arrhythmia detection algorithms and sequential therapies are reinitialized,─therapies start with the least aggressive program for each area.The other parameters remain at their programmed value, including the ventricular paced chamber parameter.The magnet rate values are as follows:Magnet rate (bpm) 96 94 91 89 87 85Magnet period (ms) 625 641 656 672 688 703Magnet rate (bpm) 83 82 80 78 77Magnet period (ms) 719 734 750 766 78115.3. RESPONSE IN THE PRESENCE OF INTERFERENCEIf the defibrillator senses electrical noise at a frequency above 16 Hz, it switches to an asynchronous mode at the basic rate. The programmed mode is restored as soon as the noise is no longer detected.Ventricular pacing is also inhibited by ventricular noise. It can be restored by setting the parameter V pacing on noise to Yes.SORIN – INTENSIA CRT-D 174 – U151A 37
15. SPECIAL MODES15.4. DETECTION CHARACTERISTICS IN THE PRESENCE OF ELECTROMAGNETIC FIELDSPer Clause 27.4 of Standard EN 45502-2-2, detection in the presence of electromagnetic fields is characterized as follows:─Differential mode:─Common mode rejection ratio:16.6 Hz 50 Hz 60 HzAtrial channel ≥ 75 dB 64 dB 62 dBVentricular channel ≥ 69 dB ≥ 57 dB ≥ 56 dBModulated interference:For atrial sensitivity setting of 0.2 mV, compliance to the Cenelec standard 45502-2-2 is met for a maximum test signal amplitude of 8 V for the frequency of 60 MHz. 0.4 mV complies with the standard for the whole frequency range.15.5. PROTECTION AGAINST SHORT-CIRCUITSThe defibrillator can undergo a short-circuit if the anode and cathode are not adequately separated.In this case, the shock is aborted to prevent damaging the defibrillator and a warning will indicate that a short circuit (shock impedance < 20 ohms) was detected during the last shock.38 SORIN – INTENSIA CRT-D 174 – U151A
16. MAIN FUNCTIONS 16. MAIN FUNCTIONS16.1. AUTOMATIC LEAD MEASUREMENTSAutomatic pacing lead impedance measurement:A lead impedance measurement is automatically performed on atrial and ventricular leads every 6 hours. The daily mean impedance is stored for each chamber.Automatic coil impedance measurement:A coil impedance measurement is automatically performed on RV and SVC coils once a week. The result is stored in the device memory.16.2. ATRIAL TACHYARRHYTHMIA MANAGEMENTMode Switch:This function is designed to limit the acceleration and variation of ventricular rate in the presence of atrial arrhythmia.16.3. VENTRICULAR TACHYARRHYTHMIA MANAGEMENTVentricular tachyarrhythmia prevention:Set of algorithms that can be used to avoid the circumstances of ventricular tachyarrhythmia onset.Searching for a long cycle (P And R based Arrhythmia Detection+: PARAD+):Additional arrhythmia classification criterion to improve identification of atrial fibrillation and avoid inappropriate shocks.Fast VT treatment:Applies detection criteria on fast ventricular tachycardia that are different from those of the VT zone, as well as different therapies. The fast VT zone is included in the VF zone: its lower limit is determined by the programmed value for the VF zone and its upper limit by the programmed value for the fast VT zone.Polarity alternation on Max shock:Reverses the programmed polarity of every second shock set at maximum energy. The number, type, and energy of shocks is independently programmable by detection zone.16.4. PACINGBTO (Brady Tachy Overlap):Enables cardiac resynchronization therapy within the slow VT zone to preserve patient exercise capacity, without affecting detection or treatment of slow VTs.SORIN – INTENSIA CRT-D 174 – U151A 39
16. MAIN FUNCTIONSPost-shock mode:After any automatic shock therapy, the post-shock mode makes it possible to apply a pacing mode other than the standard antibradycardia pacing mode and/or with different pacing parameters.SafeR (AAI <> DDD) mode:Is intended to minimize deleterious ventricular pacing. The defibrillator functions in AAI mode, and temporarily switches to DDD mode upon the occurrence of AVB III, AVB II, AVB I and ventricular pause.Anti-PMT protection:Is intended to protect the patient from Pacemaker-Mediated Tachycardia (PMT) without reducing atrial sensing capability of the device.16.5. SENSINGAutomatic Refractory Periods:Optimize sensing and make the implant progamming easier. These periods are composed of a minimal Refractory Period and a triggerable Refractory Period. The duration of the refractory periods lengthens automatically as needed.Committed period:In DDI or DDD modes, the committed period is a non-programmable 95 ms ventricular relative refractory period that starts with atrial pacing. If a ventricular event is sensed during the committed period, but outside the blanking period, the ventricle is paced at the end of the committed period. The committed period prevents inappropriate ventricular inhibition if crosstalk occurs. Protection against noise:Allows the distinction between ventricular noise and ventricular fibrillation. If the device senses ventricular noise, the ventricular sensitivity is decreased until noise is no longer detected. Ventricular pacing can be inhibited to avoid a potential paced T-wave.Automatic sensitivity control:Optimizes arrhythmia detection and avoids late detection of T-waves and over-detection of wide QRS waves. The device automatically adjusts the sensitivities based on the ventricular sensing amplitude. In case of arrhythmia suspicion or after a paced event, the programmed ventricular sensitivity will be applied. The minimum ventricular sensitivity threshold is 0.4 mV (minimum programmable value).16.6. FOLLOW-UP FUNCTIONStorage of memory data:AIDA+ (Automatic Interpretation for Diagnosis Assistance) software provides access up to 6 months of patient follow-up with day by day data collection, or up to 24 hours with hourly data collection. Episodes of ventricular tachyarrhythmia are recorded with the programmable EGM channels: either by selecting up to two traces, or by selecting "Double V" which enables a one-channel recording that is twice as long.Alerts / Warnings:The device routinely performs security self-checks and technical measurements to ensure system integrity. When system integrity is found to be at risk outside a follow-up, alerts are 40 SORIN – INTENSIA CRT-D 174 – U151A
16. MAIN FUNCTIONSstored in the device memory. When system integrity is found to be at risk during a follow-up, the information is managed as a warning (pop-up message) to notify immediately the user. For example, the following types of event can trigger a warning or an alert: technical problem during a shock, pacing lead impedance or coil impedance measurements out-of-range, battery depletion, …16.7. REMOTE MONITORING FUNCTIONRemote monitoring enables the automatic remote transmission of implant data to the physician thanks to the wireless Radio Frequency (RF) communication ability of the implant in order to provide a comprehensive report to the physician about device functioning and patient cardiac status without having the patient physically in the clinic.The data is transmitted from the implant and the SMARTVIEW monitor, a small transmitter placed in the patient home.Implant data are first transmitted to the SMARTVIEW monitor via RF. Data are then rooted through the phone line to an internet website. This website is responsible for transforming the implant data into a comprehensive report that can be consulted by the physician.16.7.1 . SMARTVIEW MonitorThe SMARTVIEW monitor is a small device equipped with an RF transmission module to communicate with the implant and a modem to export data through the internet.The SMARTVIEW monitor is delivered to the patient who has to install it at home. Preferably the SMARTVIEW monitor will be placed on the nightstand of the patient, as close as possible to the side of the bed the patient usually sleeps. The SMARTVIEW monitor shall be connected to the phone line of the patient and the power plug. Regular transmissions are done during the night when the patient is asleep next to the SMARTVIEW monitor without any intervention from the patient. 16.7.2 . Transmission triggerThere are 3 different triggers for a remote transmission:─the remote follow-up transmission is scheduled by the physician to occur regularly (according to the programming).─the alert transmission will take place when the implant has recorded an abnormal event. The list of abnormal event is available in a following paragraph. Alert conditions are checked daily.─the on-demand follow-up transmission is triggered by the patient himself through the use of a specific button on the remote-monitor.16.7.3 . Data transmittedThe data transmitted are identical to the data available during a standard interrogation with the dedicated programmer. All counters, histograms, IEGMs and diagnosis available in the device are transmitted containing (not exhaustive list):─programmed parameters─Information on patient and system implanted─battery status─lead status (brady leads and defibrillation coils) ─pacing counters and mean heart rate (brady)SORIN – INTENSIA CRT-D 174 – U151A 41
16. MAIN FUNCTIONS─atrial and ventricular arrhythmia counters and episodes─ventricular therapy countersData are presented in the form of 2 reports to the physician: the first one contains a summary of major counters, histograms, warnings and diagnosis. The second one presents the 3 most important IEGM episodes automatically selected based on the degree of severity for the patient.16.7.4 . User websiteOn the website, the physician is able to:─consult and schedule the remote follow-ups of their patient─configure additional ways of being notified of alerts (for instance by SMS, fax or e-mail─consult, print and export patient reports 16.7.5 . Alert systemThe following set of alert trigger can be independently programmed ON/OFF by the physician using the dedicated programmer and can trigger an alert transmission:─Low or high impedance (A, RV, LV)─Abnormal coil impedance (shock lead)─Low or High shock impedance─Inefficient high energy shock─All shocks programmed OFF─Shock treated VT/VF─Lack of V pacing in CRT device─Suspicion of noise on the V lead─AT/AF occurrence─Fast V rate during AT/AF42 SORIN – INTENSIA CRT-D 174 – U151AWARNING: The use of remote monitoring does not replace regular follow-up. Therefore, when using remote monitoring, the time period between follow-ups visits may not be extended.
17. PATIENT FOLLOW-UP 17. PATIENT FOLLOW-UP17.1. FOLLOW-UP RECOMMENDATIONSBefore the patient is discharged and at each subsequent follow-up visit, it is advisable to:─check the occurrence of system warnings─check the battery status,─check the integrity of the pacing and defibrillation leads,─check for proper sensing (sensitivity, crosstalk) and pacing ; set the pacing amplitude to twice the pacing threshold,─interrogate the implant memories (AIDA+),─check the efficacy of the therapies delivered,─keep a printout of programmed parameters, test results, and memory data,─reset the memory data and statistics.These operations should be performed by medical personnel in an appropriate care unit, with resuscitation equipment present.It is recommended that a routine follow-up examination be done one month after discharge, and then every three months until the device nears the replacement date.After a device reset, the magnet rate is equal to 87 bpm; it will be updated within the next 24 hours.Refer to the online help for a description of displayed warning, and the necessity to contact Sorin for an evaluation.Implant software upgrade:In case a new implant software is downloaded in the device memory through the programmer, a warning message could be displayed by the programmer to inform the user and give the proper instructions to follow.17.2. HOLTER FUNCTIONThe Holter records up to 14 tachyarrhythmia episodes as well as the therapy history.Stored EpisodesINTENSIA CRT-D 174 stores up to 14 episodes (VF, VT, Slow VT, SVT/ST, non-sustained).For each episode four levels of details are presented:─Tachogram (to visualize PP and PR intervals)─Event log for the entire episode: ─PARAD/PARAD+ analysis for each majority,─Delivered therapies,SORIN – INTENSIA CRT-D 174 – U151A 43NOTE: If the last reforming, charge or shock occurred during the week preceding the interrogation, the last battery value may be still impacted by the event. One week post event, the battery will recover its steady state value.
17. PATIENT FOLLOW-UP─Markers: Atrial, ventricular and biventricular markers, sensed, paced and in relative refractory periods,─EGM: onset and detection of the arrhythmia, on two therapies, and the return to slow rhythm by recording electrogram.Therapy historyFor each arrhythmia detection, each therapy delivered (either automatically or during an electrophysiological study) and at the end of each arrhythmia, INTENSIA CRT-D 174 records the type of majority rhythm, the number of ATP sequences delivered, the energy and the number of shocks delivered.17.3. RECOMMENDED REPLACEMENT TIME (RRT)Recommended Replacement Time (RRT)(1) is controlled by:─magnet rate equal to 80 ± 1 bpm or─battery voltage equal to 2.66 V ± 0.01 VBetween the RTT and the EOS (End of Service)(2), INTENSIA CRT-D 174 can still function for:─7.4 months (100% atrial and biventricular pacing in DDD mode, 500 ohms, with as-shipped settings), and deliver 7 shocks at 34 J or─6.4 months (0% pacing, sensors OFF, one 42 J shock every 2 weeks).Once the Recommended Replacement Time (RRT) point has been reached, the device operates normally, except that the charge time increases. Under normal conditions (and without programmer use) the charge times are as follows:Shock energy Charge time (sec)BOS(3) 42 J 10 (± 2)RTT 42 J 13 (± 3)(1) Recommended Replacement Time (RRT) corresponds to Elective Replacement Indicators (ERI) previously used.(2) End of Service (EOS) corresponds to End of Life (EOL) previously used.(3) Beginning of Service (BOS) corresponds to Beginning of Life (BOL) previously used.17.4. EXPLANTATIONThe defibrillator should be explanted in the following cases:─The Recommended Replacement Time (RRT) point is reached─Confirmed malfunction─Burial of the patient (for environmental reasons, the local regulation may require the explantation of the devices containing a battery supply)─Cremation of the patient (the defibrillator may explode if placed in an incinerator)The explanted defibrillator should not be reused in another patient.44 SORIN – INTENSIA CRT-D 174 – U151ACAUTION: The defibrillator should be replaced as soon as the Recommended Replacement Time (RRT) point is reached.
17. PATIENT FOLLOW-UPAll explanted defibrillators should be returned to Sorin, carefully cleaned of all traces of contamination. This may be done by immersing them in an aqueous sodium hypochlorite containing at least 1% chlorine, followed by rinsing copiously with water.The defibrillator should be protected against mechanical impact and the temperature variations that may occur during shipping.Before explantation, it is advisable to:─print out all programmed parameters, statistics and Holter function report,─save Patient data on floppy disk or hard disk,─disable shock therapies (VT and VF) to avoid any risk of untimely shock.17.5. DEFIBRILLATOR IDENTIFICATIONThe defibrillator can be interrogated and programmed via telemetry, using the programming head interfaced with the Sorin dedicated programmer.Position the programming head over the telemetry antenna located in the upper part of the device, in order to communicate effectively via telemetry (see diagram below).The device can be non-invasively identified as follows:1. Take an x-ray to identify the name of the manufacturer and model, printed on the device (X-ray ID is SDE : S = SORIN ; D = Defibrillator ; E = INTENSIA range). 2. Interrogate the device using the Sorin dedicated programmer. The model and serial number of the device are automatically displayed. The first figure in the serial number corresponds to the last figure in the year of manufacture.SORIN – INTENSIA CRT-D 174 – U151A 45
18. SUPPLEMENTAL INFORMATION 18. SUPPLEMENTAL INFORMATIONClinical data presented in this section are from the SafeR (AAI <> DDD) clinical study. SafeR (AAI <> DDD) operation in INTENSIA is similar to that in the Symphony pacemaker. The data provided are applicable to INTENSIA CRT-D 174.18.1. ADVERSE EVENTS IN THE SAFER (AAI <> DDD) STUDYClinical study of the SafeR (AAI <> DDD) included 45 Symphony 2550 devices implanted in 45 patients. No serious adverse events were device- or feature-related. There were no deaths in the study.Table 1: Summary of Symphony safety data during studyPatients Number of eventsNumber of patients% of patients Number of eventsEvents per device year (a)Deaths 0 0 0 0Explants 0 0 0 0Serious pacemaker related events outside the use of SafeR (AAI <> DDD)0000Non-serious pacemaker related events outside the use of SafeR (AAI <> DDD)0000Serious events due to the use of SafeR (AAI <> DDD)0000Non-serious events related due to the use SafeR (AAI <> DDD)13 28.9 15 3.2Serious non-pacemaker related events6 13.3 9 1.9Non-serious non-pacemaker related events8 17.8 8 1.7(a) 4.74 device yearsNon-serious events due to the use of SafeR 2 (AAI <> DDD) included: delay in switching on 2nd degree AV block, inappropriate classification of a PAC, disagreement between markers and recorded EGM, atrial pacing above the maximum rate, recycling on an R-wave in a 46 SORIN – INTENSIA CRT-D 174 – U151A
18. SUPPLEMENTAL INFORMATIONrefractory period, and disagreement in the statistics for swuitches to DDD. No patient symptoms were associated with these events.18.2. SAFER (AAI <> DDD) CLINICAL STUDYSafeR (AAI <> DDD) mode in INTENSIA is similar to that in Symphony.The differences in SafeR (AAI <> DDD) mode between the two devices are:─To prevent long RR intervals during VT/VF, SafeR (AAI <> DDD) has no effect during VT/VF therapy, electrophysiologic studies, and post-shock recovery.─The maximum acceptable AV delay for first degree AV block varies as a function of pacing rate.─INTENSIA requires a ventricular sensed event to atrial paced event (RA) interval of at least 100 ms. Therefore, the device lengthens the atrial escape interval so that it ends at least 102 ms after the ventricular event.─During atrial fibrillation episode, pause criterion is fixed to 2s to avoid long bradycardia episodes in switching to DDD mode.Despite these differences, the data collected on Symphony devices are applicable to INTENSIA because the principles of SafeR (AAI <> DDD) operation did not change. The criteria for switching from AAI to DDD (or vice versa) did not change. The device’s method for evaluating the presence of AV conduction did not change.Methods:All patients were implanted with a Symphony Model 2550 dual-chamber rate-responsive pacemaker with SafeR (AAI <> DDD) mode. A variety of marketed atrial and ventricular pacing leads were used. The pacemaker was programmed and interrogated via bi-directional telemetry using a Sorin dedicated programmer and a CPR3 programming head.The study’s routine evaluation consisted of enrollment, pre-discharge evaluation, and a scheduled follow-up visit at one month. At pre-discharge, a 24-hour Holter recording was performed and pacemaker memory was read. At one month, pacemaker memory was read. Investigators also documented adverse events.Patients studied:A total of 45 patients from 12 centers had Symphony 2550 pacemakers with SafeR (AAI <> DDD). Of these, 14 (31 %) were female and 31 (69 %) were male. Mean patient age (± SD) was 74 ± 9 years.Primary indications for implant were: 1st degree AV block (11.1 %), 2nd degree AV block (6.7 %), 3rd degree AV block (22.2 %), sinus node dysfunction (62.2 %) or other (6.7 %).Effectiveness results:To determine the effectiveness of SafeR (AAI <> DDD) mode, the percentage of ventricular pacing provided over one month was recorded from pacemaker memory.Thirty-five patients contributed data to evaluate the percentage of ventricular pacing provided with SafeR (AAI <> DDD). Twenty-nine patients had 1 % or less ventricular pacing and six patients had a range of 28-97 % ventricular pacing. The graph below shows the distribution of ventricular pacing observed in patients with and without AV block as a primary indication for implant.SORIN – INTENSIA CRT-D 174 – U151A 47
18. SUPPLEMENTAL INFORMATIONThe graph shows that many patients programmed to SafeR (AAI <> DDD) had less than 1% ventricular pacing:─84 % of patients without AV block at implant.─63 % of patients with AV block at implant.In a representative reference group(1) of patients programmed to DDD, none had less than 1 % ventricular pacing and only 10 % had less than 90 % ventricular pacing regardless of AV block indication at implant.The actual reduction of ventricular pacing that SafeR (AAI <> DDD) provides in an individual will depend on the amount of time that the patient spends in AV block. SafeR (AAI <> DDD) cannot and should not provide any decrease in ventricular pacing while the patient is in AV block.(1) Pioger G, Jauvert G, Nitzsché R, Pozzan J, Laure H, Zigelman M, Leny G, Vandrell M, Ritter P, and Cazeau S. Incidence and predictive factors of atrial fibrillation in paced patients. PACE, 28, Supp 1: S137-141; January 2005. This was a prospective observational study of 377 patients with a functionally similar device programmed to DDD. The primary indications for implant were: AV block (49 %), sinus node disease (16 %), brady-tachy syndrome (5 %), AV block + sinus node disease (19 %), AV block + brady-tachy syndrome (6 %), and brady-tachy syndrome + sinus node disease (5 %).48 SORIN – INTENSIA CRT-D 174 – U151A

Shock (42 J) 1-2-3-421.4. REMOTE ALERTS AND WARNINGSThe device routinely performs security self-checks and technical measurements to ensure system integrity. When system integrity is found to be at risk outside a follow-up, alerts are stored in the device memory. When system integrity is found to be at risk during a follow-up, the information is managed as a warning (pop-up message) to notify immediately the user. For example, the following types of event can trigger a warning or an alert: technical problem during a shock, pacing lead impedance or coil impedance measurements out-of-range, battery depletion, etc. The Remote tab presents an overview of all the alerts managed by the device.General parameters ValuesRF communication (1) ON-OFFRemote alerts (1) ON-OFF(1) RF and Remote alerts are turned on automatically if Shocks are programmed ON.When Alerts are programmed "On", the following System Alerts are automatically activated:─Battery depletion – RRT─Device reset─Excessive charge time (>25s)SORIN – INTENSIA CRT-D 174 – U151A 59

23. LIMITED WARRANTY 23. LIMITED WARRANTYThe INTENSIA implantable cardioverter defibrillator is the result of highly advanced research and all components have been selected after exhaustive testing.Sorin Group Italia S.r.l. (identified as “Sorin” hereafter) guarantees the product INTENSIA against any damage caused by component failure or production defects during a period of four years after the implantation date, and Sorin commits itself to replace all INTENSIA devices according to the terms described in article 1 and described in article 2 of this section.Sorin makes no claim that the human body will not react unsuitably to the implantation of the INTENSIA device, or that failure will never occur.Sorin does not guarantee the suitability of INTENSIA in defined types of patients; selection of the device is a medical decision.Sorin shall not be held liable for any damage indirectly associated with the INTENSIA, whether as part of normal or abnormal operation, nor damage from its explantation or replacement.Sorin does not authorise anyone to modify these limited warranty conditions.23.1. ARTICLE 1 : TERMS OF LIMITED WARRANTY1. The INTENSIA implantable cardioverter defibrillator is only guaranteed for the first implantation.2. The EURID/Eucomed implant form must be sent to Sorin within 30 days after implantation.3. The INTENSIA cardioverter defibrillator must be implanted prior to the use-before date indicated on the packaging.4. The limited guarantee only applies to suspect devices returned to the manufacturer, carefully packed and accompanied by an explantation report duly completed by the hospital or the doctor and considered defective after analysis by Sorin. The device must be returned within the 30 days following explantation to Sorin.Any device returned and replaced under the terms of this limited warranty will become the exclusive property of Sorin.Any rights under the terms of this limited warranty will be forfeited if the INTENSIA device has been opened by anyone other than Sorin.These rights will also be forfeited if the device has been damaged by carelessness or accident.This is the case especially if the device has been exposed to temperatures above 50°C, to electrical abuse or to mechanical shock, particularly as a result of being dropped. Consequently, any expert opinion offered by a third party after the device has been removed also nullifies the guarantee.5. The limited warranty will be forfeited if it is proven that the device has been misused or inadequately implanted, against the physicians’manual recommendations of INTENSIA.6. The limited warranty does not include leads and other accessories used for the implantation.7. The replacement terms or conditions described in article 2 include all devices that shall be replaced within the limited warranty period because of battery depletion, without any 62 SORIN – INTENSIA CRT-D 174 – U151A
23. LIMITED WARRANTYlink to a component failure or a production hazard. The device battery longevity varies with the type and number of delivered therapies.8. Legal requirements of jurisdictions where the INTENSIA device is distributed will supersede any warranty conditions indicated in this manual that conflict with such laws.23.2. ARTICLE 2 : TERMS OF REPLACEMENT1. In case of INTENSIA failure because of a component failure, a production defect, or a conception error, occurring within two-year period starting from the implantation date, Sorin is committed to: ─replacing free of charge the explanted device by a Sorin device with equivalent features,─or issuing a replacement credit equal to the purchase price for the purchase of any other Sorin replacement device.2. After a two-year period and up to 4 years after the implantation, Sorin, because of limited warranty terms, will issue a replacement credit to the buyer of an amount equivalent to half of the initial purchase price minus prorata temporis during this two-years period.3. In any case the credit issued by the limited warranty terms cannot exceed the purchase price of a Sorin replacement device.SORIN – INTENSIA CRT-D 174 – U151A 63
