Introduction1IntroductionManual OverviewThis manual provides basic information for the implantation and operation of the Precision™ Implantable Pulse Generator (IPG), Model SC-1110. This information includes an overview of accesso-ries for programming and powering the IPG, clinical and surgical con-siderations, storage and handling requirements, and relevant precautions concerning an implanted neurostimulator. Additional information on system components and operation can be found in the BionicNavigator™ Software Guide.Device DescriptionThe Advanced Bionics® Precision implantable pulse generator system is intended to treat chronic pain by electrically stimulating the spinal cord. The multi-channel, multi-electrode device capability provides flexibility in conjunction with ease of programming. A rechargeable battery increases IPG longevity and output capability while reducing size and device replacement surgeries. The implant is controlled by a handheld Remote Control, and can be engaged by a clinician com-puter using proprietary BionicNavigator software. Periodically, the implant battery requires replenishing with an RF charging device pro-vided in the Patient Take Home Kit SC-6000-02.Features • Stimulation electrode field navigation• Sixteen independent current-controlled electrodes• Four programmable stimulation areas per program; four possible programs• Long-life operation• High-range parameter capability•Small size• Two-foot programming range
2Physician Implant ManualIndications for UseThe Advanced Bionics PRECISION™ Spinal Cord Stimulator System (PRECISION™ System) is indicated as an aid in the management of chronic intractable pain of the trunk and/or limbs, including unilateral or bilateral pain associated with the following: failed back surgery syndrome, intractable low back pain and leg pain.Precision System Clinical SummaryDetermination of the safety and effectiveness of the PRECISION Sys-tem was based on available published clinical studies for similar implanted spinal cord stimulation systems. The PRECISION System is similar to the SCS systems reported in published literature in intended use, target patient population, technology, device design, and output characteristics. Therefore, the clinical data from the published literature described below represents evidence supporting the safety and effectiveness of the PRECISION System for the treatment chronic intractable pain of the trunk and/or limbs, including unilateral or bilateral pain associated with the following: failed back surgery syndrome, intractable low back and leg pain.Efficacy EvaluationThree (3) clinical literature studies were used to support the effective-ness of the PRECISION System (Ohnmeiss et al. 1996, Villavincen-cio et al. 2000, Hassenbach SJ et al. 1995). The studies included a total of 116 patients that were implanted with an SCS system. A total of approximately 3166 device months of experience was depicted from the retrospective clinical evaluation. All three studies examined the effectiveness of SCS on patients with chronic pain of the trunk and/or limbs including unilateral or bilateral pain associated with the following: failed back surgery syndrome or intractable low back and leg pain. In all studies, a totally implantable spinal cord stimulator was used in association with a percutaneous and/or surgical lead. These studies provide the same diagnostic or therapeutic intervention
Introduction3for the same disease/conditions and patient population as the PRECI-SION System.The prospective study by Ohnmeiss et al. 1996, examined the long-term effectiveness of SCS in patients with intractable leg pain. Forty patients were implanted with SCS systems and evaluated at 6 weeks, 12 months, and 24 months follow-up. Outcome measures included the VAS, pain drawings, medication use, SIP (Sickness Impact Profile), isometric lower extremity testing, and patient questionnaires. An intent-to-treat analysis was performed. After patients had SCS for 24 months, leg pain, pain when walking, standing pain, pain’s effect on overall lifestyle, and the total analog scale scores were significantly improved from baseline. In this study, 25% of the implanted patients had greater than 50% improvement in pain rating.In addition, 3 patients from this study had their stimulators reposi-tioned due to pain at the original location. Three patients had reopera-tions to adjust lead position; 1 patient required 2 reoperations, 1 patient had the device removed due to infection and later to have a new device implanted. A diabetic patient had skin problems which required device removal; a new device was later implanted. Two patients had the device removed due to unsatisfactory pain relief.The prospective study performed by Villavicencio et al. 2000 included 41 patients with pain of various etiologies. The majority of the patients, 24 (59%), had Failed Back Surgery Syndrome (FBSS), 7 (17%) had Complex Regional Pain Syndrome (CRPS I and II), 4 (10%) had neuropathic pain syndrome, and 6 (15%) were diagnosed as stroke or other. Patients underwent an initial trial period for SCS with temporary leads. If the trial resulted in greater than 50% reduc-tion in the patient’s pain, as measured by the VAS, the patient was implanted with a SCS system. In this study, 27/41 patients, 66%, had permanent implants. All patients were examined after 6 weeks. Pain measurements were assessed at 3-6 month intervals for the first year and annually thereafter. The median long-term follow-up was 34 months. A total of 24/27 (89%), reported greater than 50% reduction
4Physician Implant Manualin pain. Since the majority of the patients were treated for FBSS, this article supports the use of SCS for the treatment of FBSS.In this study, one patient required a revision because of electrode frac-ture. One patient required removal of the system due to local infec-tion. One patient required replacement of the IPG due to mechanical failure. Overall, 16 of 27 (59%) patients required a total of 36 reposi-tioning procedures. A retrospective analysis performed by Hassenbusch SJ et al. 1995 included patients with chronic lower body pain, predominately neuro-pathic pain and pain either midline lower back and/or unilateral or bilateral leg pain treated over a 5 year period. The study was a com-parison of SCS to spinal infusion of opiods. For patients with radicu-lar pain involving one leg with or without unilateral buttock pain, a trial of SCS was recommended first. For patients with midline back pain and /or bilateral leg pain, a trial of long-term spinal infusion was recommended first. If the patients failed screening with either of these modalities, the other was then tested. If the treatment reduced the pain by 50%, the systems were internalized. A retrospective analysis of patients with unilateral leg and/or buttock pain treated initially with SCS and bilateral leg or mainly low back pain treated initially with spinal infusions of opioids was then done.In this study, 42 patients were screened; 26 (62%) patients received spinal stimulation; 16 (38%) received opioids via a spinal infusion pump. Five patients did not receive adequate pain relief with SCS; 3 (7%) of these patients underwent trial spinal infusions and had effec-tive pain relief. There were 4 (10%) patients who underwent a trial of spinal infusion of opioid but did not receive adequate pain relief; these patients were not tested with SCS. Pain severity was rated using a verbal digital pain scale: “On a scale of 0 to 10 where 0 is no pain and 10 is the worst pain you could ever imagine, what is your pain now?” 16/26 patients (62%) had greater than 50% pain relief with SCS. In this study, 2/16 (13%) had greater than 50% pain relief with
Introduction5opioids. Mean follow-up was 2.1 + 0.3 years. This analysis supports the use of SCS for intractable low back and leg pain.In this study, 7 (17%) patients suffered complications after implanta-tion of the device; 5 (12%) patients required repositioning of catheter type electrodes and 2 patients required revision of the stimulator gen-erator.Safety EvaluationEleven studies were identified based on the detailed inclusion/exclu-sion criteria to demonstrate the safety of the PRECISION System. The studies included a total of 1056 patients that were trialed with SCS systems and 880 patients that received implants. The table below depicts the number of patients, the number of events, and the percent-age of occurrences of each event compared to the total number of patients. It should be noted that citations cover both IPG and RF Sys-tems. The clinical experience reported in the literature on RF systems is relevant to determining the safety of totally implantable IPG sys-tems.Table 1: Summary of Risks Identified in the Retrospective Clinical StudiesRisks# Patients With Adverse EventIntent-to-Treat BasisN = 1056Implanted Patient BasisN = 880Lead Migration 175 16.6% 19.9%Infection 39 3.7% 4.4%Epidural Hemorrhage 0 0% 0%Seroma 0 0% 0%Hematoma 1 0.1% 0.1%Paralysis 0 0% 0%CSF Leak 5 0.5% 0.6%

Safety Information9Safety InformationWarningsMagnetic Resonance Imaging (MRI). Patients implanted with the Precision SCS system should not be subjected to MRI. MRI exposure may result in dislodgement of implanted components, heating of the neurostimulator, damage to the device electronics and/or voltage induction through the leads and stimulator causing an uncomfortable or “jolting” sensation.Pediatric Use. The safety and effectiveness of spinal cord stimula-tion has not been established for pediatric use.Diathermy. Shortwave, microwave and/or therapeutic ultrasound diathermy should not be used on SCS patients. The energy generated by diathermy can be transferred through the stimulator system, caus-ing tissue damage at the lead site and resulting in severe injury or death. The IPG, whether it is turned on or off, may be damaged.Implanted Stimulation Devices. Spinal cord stimulators may interfere with the operation of implanted sensing stimulators such as pacemakers or cardioverter defibrillators. The effects of implanted stimulation devices on neurostimulators is unknown.Implant Damage. Burns may result if the pulse generator case is ruptured or pierced and patient tissue is exposed to battery chemicals. Do not implant the device if the case is damaged.Postural Changes. Patients should be advised that changes in pos-ture or abrupt movements may cause decreases, or uncomfortable or painful increases in the perceived stimulation level. Patients should be advised to turn down the amplitude or turn off the IPG before mak-ing posture changes. If unpleasant sensations occur, the IPG should be turned off immediately.
10Physician Implant ManualElectromagnetic Interference. Strong electromagnetic fields can potentially turn the stimulator off, or cause uncomfortable or jolting stimulation. Patients should be counseled to avoid or exercise care around:• Theft detectors or security screeners such as those used at entrances/exits of department stores, libraries, and other public establishments, and/or airport security screening devices. It is recommended that patients request assistance to bypass the device. If they must pro-ceed through the device, the patient should turn off the stimulator and proceed with caution, ensuring to move through the center of the screener as quickly as possible.• Power lines or power generators• Electric steel furnaces and arc welders• Large, magnetized stereo speakersPrecautionsPhysician training is required.Medical Devices/Therapies. The following medical therapies or procedures may turn stimulation off or may cause permanent damage to the implant, particularly if used in close proximity to the device:• lithotripsy• electrocautery: Do not use monopolar cautery.• external defibrillation• radiation therapy• ultrasonic scanning• high-output ultrasoundIf any of the above is required by medical necessity, refer to “Instruc-tions for the Physician” on page 15. Ultimately, however, the device may require explantation as a result of damage to the device.
Safety Information11Automobiles and Other Equipment. Patients should not operate automobiles, other motorized vehicles, or potentially dangerous machinery/equipment with therapeutic stimulation switched on. Stim-ulation must be turned off first. Sudden stimulation changes, if they occur, may distract patients from attentive operation of the vehicle or equipment.Cell Phones. While we don’t anticipate any interference with cell phones, the full effects of interaction with cell phones are unknown at this time.Post Operative. During the two weeks following surgery, it is important to use extreme care so that appropriate healing will secure the implanted components and close the surgical incisions: Do not exercise or attempt to move heavy objects, and avoid deep bending and stretching. Temporarily, there may be some pain in the area of the implant as the incisions heal. If discomfort continues beyond two weeks, contact your physician. If you notice excessive redness around the wound areas during this time, contact your physician to check for infection and administer proper treatment. In rare cases, adverse tis-sue reaction to implanted materials can occur during this period.Implant Location. Never attempt to change the orientation or “flip” the implant. Do not “finger” or play with the implant. If the implant flips over in your body it cannot be charged. If you know that the device has turned, or if stimulation cannot be turned on after charging, contact your physician to arrange an evaluation of the system. In some cases, the skin over your implant may become very thin over time. If this occurs, contact your physician. Lead Location. In some instances a lead can move from its original location, and stimulation at the intended pain site can be lost. If this occurs, consult your physician who may able to restore stimulation by reprogramming the implant in the clinic or repositioning the lead dur-ing another operation.
12Physician Implant ManualDevice Failure. Implants can fail at any time due to random compo-nent failure, loss of battery functionality, or lead breakage. If the device stops working even after complete charging (up to four hours), turn off the implant and contact your physician so that the system can be evaluated.Storage. Do not expose the Remote Control or Charging System components to excessively hot or cold conditions. Do not leave the devices in your car or outdoors for extended periods of time. The sen-sitive electronics can be damaged by temperature extremes, particu-larly high heat. If the Remote Control or the Charging System is to be stored for a period of time, be careful that the storage temperature does not exceed -20–60 °C (-4–140 °F).Handling. Handle the system components and accessories with care. Do not drop them or submerge them in water. Although reliability testing has been performed to ensure quality manufacturing and per-formance, dropping the devices on hard surfaces or in water, or other rough handling, can permanently damage the components. (See “Lim-ited Warranty” on page 54.)Component Disposal. Do not dispose of the Remote Control or Charger in fire. The battery in these devices can explode in fire. Dis-pose of used batteries in accordance with local regulations. The IPG should be explanted in the case of cremation, and returned to Advanced Bionics.Remote Control, Charging System Cleaning. The components can be cleaned using alcohol or a mild detergent applied with a cloth or tissue. Residue from soapy detergents should be removed with a damp cloth. Do not use abrasive cleansers for cleaning.
Safety Information13Adverse EffectsPotential risks are involved with any surgery. The possible risks of implanting a pulse generator as part of a system to deliver spinal cord stimulation include:• Lead migration, resulting in undesirable changes in stimulation and subsequent reduction in pain relief.• System failure, which can occur at any time due to ran-dom failure(s) of the components or the battery. These events, which may include device failure, lead breakage, hardware malfunctions, loose connections, electrical shorts or open circuits and lead insulation breaches, can result in ineffective pain control.• Tissue reaction to implanted materials can occur.• Skin erosion at the IPG site can occur over time.• Possible surgical procedural risks are: temporary pain at the implant site, infection, cerebrospinal fluid (CSF) leakage and, although rare, epidural hemorrhage, seroma, hematoma and paralysis.• External sources of electromagnetic interference may cause the device to malfunction and affect stimulation.• Exposure to MRI can result in heating of tissue, image artifacts, induced voltages in the neurostimulator and/or leads, lead dislodgement.• Undesirable stimulation may occur over time due to cel-lular changes in tissue around the electrodes, changes in electrode position, loose electrical connections and/or lead failure.• The patient may experience painful electrical stimula-tion of the chest wall as a result of stimulation of certain nerve roots several weeks after surgery.
14Physician Implant Manual• Over time, the implant may move from its original posi-tion.• Weakness, clumsiness, numbness or pain below the level of implantation.• Persistent pain at the IPG or lead site.
Safety Information15Instructions for the PhysicianImplanted Stimulation Devices. If such implanted devices are indicated for the patient, careful screening is required to determine if safe results can be achieved before permanently implementing con-current electrical therapies.Postural Changes. Depending on the activity level of the patient, postural changes may affect stimulation intensity. Instruct patients to keep the Remote Control at hand at all times, and ensure that they understand how to adjust stimulation levels.Medical Devices/Therapies. If the patient is required to undergo lithotripsy, electrocautery, external defibrillation, radiation therapy, ultrasonic scanning, or high-output ultrasound:• Turn off stimulation at least five minutes before the pro-cedure or application.• All equipment, including ground plates and paddles, must be used as far away from the IPG as possible.• Bipolar electrocautery is recommended. Do not use monopolar electrocautery.• Every effort should be taken to keep fields, including current, radiation, or high-output ultrasonic beams, away from the IPG.• Equipment should be set to the lowest energy setting clinically indicated.• Instruct patients to confirm IPG functionality following treatment by turning on the IPG and gradually increas-ing stimulation to the desired level.Sterilization• Before implanting the IPG, inspect the condition of the sterilization indicator and the sterile package before
16Physician Implant Manualopening the package and using the contents. Do not use the contents if the indicator lines are not red, if the pack-age is broken or torn, or if contamination is suspected because of a defective sterile package seal. • Do not resterilize the IPG. If resterilization is required, obtain a sterile device for implantation.• The IPG is for single use only. Do not reuse.
Safety Information17HandlingHandle the IPG and implanted accessories with care. • Keep sharp instruments away from the components. • Do not use the IPG if it has been dropped on a hard sur-face from a height of more than one foot.• Do not incinerate an IPG. Improper disposal of the device could result in an explosion. Devices should be explanted in the case of cremation, and returned to Advanced Bionics Corporation.Storage• Store the IPG between 0° C and 45° C (32° F and 113° F). Devices should always be kept in temperature regulated areas within the acceptable temperature range. IPG damage can occur at temperatures outside of this range.

20Physician Implant ManualGuidelines for Permanent ImplantationThis section details the procedures for • tunneling the lead/extension as part of an IPG implant, and• connection of lead/extension to the IPG.The Tunneling Tool Assembly used in this procedure is provided with the Precision device as part of the IPG Kit. Percutaneous Lead/Extension RemovalBefore revising a trial system for chronic stimulation, the nonsterile portion of the lead or extension must be removed. The method chosen from the choices below will depend upon how the patient was pre-pared for the trial phase.Remove bandages and properly cleanse the exit site.Option A. Temporary Lead RemovalRemove the lead(s) completely and discard them.Option B. Extension Removal1. Open the midline incision to expose the lead and connector.
Guidelines for Permanent Implantation212. Cut the lead extension at the connector. 3. Pull the lead extension through the tunnel and away from body at the externalized site.4. Loosen the connector setscrew using the torque wrench provided. Disconnect and discard the connector.Note: Connect a new lead extension, if necessary, to reach the selected IPG site.
22Physician Implant ManualIPG Implantation1. Ensure that the area surrounding the lead entry site is incised to a dimension that will accommodate the tunneling tool. Check that the lead is securely sutured with the suture sleeve. 2. Select and mark the intended IPG site several inches away from the previously externalized leads, and create an incision at the top of the implant site. (Common sites are the abdomen, upper but-tock, or subclavicular area.)3. Create a subcutaneous pocket no larger than the IPG outline at a depth less than 3/4 inch (2.0 cm) from the surface. Note: • Using the template will help guide the correct pocket sizing. It is important to keep the pocket small to reduce the chances of patient manipulation and IPG flipping.•Implant charging could become ineffective at depths greater than 3/4 inch (2.0 cm).
Guidelines for Permanent Implantation23Tool AssemblyThe tunneling tool provided with the IPG includes a shaft extender to be used for up to two leads.1. Attach the handle to the tunneling tool shaft by turning the lock-ing mechanism clockwise.Note: For more length, attach the shaft extension to the handle, and then attach the carrier shaft.2. Thread the tip cover onto the tunneling tool and tighten by turn-ing clockwise. Tunneling The Lead 1. Mark the desired route of the tunnel.2. Administer the appropriate local anesthetic along the tunneling path.Tool HandleLocking MechanismLocking MechanismShaft ExtensionShaftCarrier Tip Cover
24Physician Implant ManualNote: Check that the tunneling tool tip is securely threaded onto the carrier.3. OPTIONAL. If necessary, bend the tool shaft to conform to the patient’s body. CAUTION: Do not bend locking joints.4. Create a subcutaneous tunnel from the IPG site to the midline incision.Note: Deep tunneling is not recommended.
Guidelines for Permanent Implantation255. Once the tunneling tip is completely exposed at midline, press it toward the shaft and turn it counterclockwise to remove it for access to the carrier. Note: You may feel the tip slide back before the cover begins to unscrew.
26Physician Implant Manual6. Carefully position each lead or extension into the carrier shaft and press the lead/extension into the groove.Note: If necessary, swivel the carrier by pulling it away from the handle and turning it to get better access to the cavities. 7. Gently pull the tunneling tool back through the tunnel.
Guidelines for Permanent Implantation278. Gently lift the lead(s) out of the locking groove(s). 9. Wipe off any fluids from the proximal end of the lead(s). Connecting To the IPGDual Lead Connection• Superior (upper or left) leads connect to IPG port 1-L.• Inferior (lower or right) leads connect to IPG port 2-R. Single Lead Connection• Connect a single lead to IPG port 1-L.• Plug port 2-R with the connector plug supplied in the IPG Kit.
28Physician Implant Manual1. Fully insert the lead(s) into the IPG port(s). When the lead is properly inserted, the lead will stop and the retention ring will be located under the setscrew. 2. Pass the torque wrench through the slit in the septum located on the top of the IPG header and tighten both set screws, one at a time, until the torque wrench “clicks,” indicating lock.
Guidelines for Permanent Implantation29CAUTION: Ensure that the lead is fully inserted before tightening the setscrew to prevent lead damage.Note: • If the connector plug is used in port 2-R, it is still necessary to tighten the setscrew as described. •The wrench is torque-limited and cannot be overtightened.•Ensure that the lead is fully inserted before tightening the setscrew to prevent lead damage.•If there appears to be an obstruction when inserting the lead, lead extension, or connector plug, use the torque wrench to loosen (counterclockwise) the setscrew and/or gently rotate the lead to help advance the proximal end.3. Place the IPG in the subcutaneous pocket with “This Side Up” facing towards the skin.4. Coil excess lead or extension under the IPG.Note: To confirm good connections, check impedances before tightening the setscrew.5. Secure the IPG in the pocket by suturing through the holes in the connector.6. Close and dress the wound(s).
30Physician Implant ManualIPG Explant or Replacement1. Turn off the IPG.2. Surgically open the IPG pocket and withdraw the device.3. Unscrew the connector setscrews to release and remove the leads. 4. For replacement, connect the new IPG following steps 1-6 of “Connecting to the IPG,” preceding. Or, to terminate therapy, sur-gically remove the implanted lead system.
Rechargable Implant System31Rechargable Implant SystemThe Precision spinal cord stimulator is rechargeable. Depending on stimulation power usage and programming, the majority of patients will need to recharge the implant once per week. High power users will require more frequent charging. Advanced Bionics recommends any recharge schedule (daily, bi-daily, weekly, bi-weekly) that fits the patient’s schedule and lifestyle while maintaining sufficient charge to maintain stimulation.The Clinician Programmer will estimate charging time based on 24 hours per day of stimulation at the programmed settings. Recharge time can range from ten minutes to four hours. Patients should be instructed to charge until the Charger emits an end of charge beep sig-nal. The recharging process is important, but simple.The rechargeable implant battery should provide at least five years of service. Over time and repeated charging, the battery in the implant will lose its ability to recover its full capacity. As a result, the implant may require increased recharge time and/or shorter intervals between charges after five years of service. The implant will need replacement when stimulation can no longer be maintained with routine charging.IPG Battery StatusWhen the patient Remote Control communicates with the implant, the battery status is sent to the remote, which will display a message when the stimulator battery is low and when the stimulator battery is empty. When the remote indicates a low battery (message: Recharge Stimulator Soon) the implant should be recharged as soon as possible. Failure to recharge will lead to loss of stimulation in less than 24
32Physician Implant Manualhours, and the implant will need to be charged for approximately two hours before reactivation.If the patient reports that stimulation has stopped but does not also report having seen the Remote Control warning messages “Recharge Stimulator Now” and “Must Recharge,” instruct the patient to check the implant battery status with the Remote Control first. If the mes-sage sequence is displayed, inform the user that the IPG must be recharged within three days or he/she runs the risk of needing to return to the clinic for reprogramming.If the patient reports seeing a “No Response” message on the Remote Control screen, the lack of communication is probably due to a low battery. Instruct the patient to recharge the implant, and then try using the remote again.Charging StepsThe Charger Base Station should be plugged in and the charger placed in the cradle until the indicator light is green. If the indicator is amber-colored, the charger may not be able to fully charge the implant. Users may wear the charger over the implant using a Velcro® belt or adhesive patches. Advanced Bionics recommends using the Velcro® belt for charging.
Rechargable Implant System331. While the Charger is seated in the Base Station, check that the indicator light is green.2. Remove the Charger from the Base Station. (The indicator light will go out, regardless of the ready status of the Charger.)Note: If the implant is not recharged as recommended, stimulation will eventually stop due to a low battery. If this happens, the implant must be recharged within three days from loss of stimulation. If stimulation stops and you have lost or cannot get to your charger within five days, contact Customer Service immediately at (866) 360-4747.If discontinuing stimulation for an extended period of time, the implant should first be fully charged. Additionally, the implant should be fully charged every month if stimulation is not used.
34Physician Implant Manual3. Apply the adhesive to the backside of the Charger by peeling the clear device side liner from the patch and applying the patch to the device, as shown, and then remove the skin side beige liner from the adhesive (only good for one fixation). ORPlace the Charger into the Velcro® belt with the power button facing out. 4. Press the power button, the large blue center of the Charger, to turn on the Charger. The indicator light will return to the status color (green or amber), and the Charger will begin beeping steadily to signal that it is searching for the implant.
Rechargable Implant System355. Locate the Charger over the IPG. When the Charger is correctly aligned with the IPG, the beeping will stop. Press the Charger with the adhesive, or secure the Velcro® belt at this time.Note: • If the Charger loses contact with the IPG during charging, the steady alignment beep will sound. Readjust the belt or reapply the adhesive.6. When the Charger emits a distinct double beep, the implant is charged.
36Physician Implant ManualPatient Remote ControlBasic OperationThe Remote Control communicates with the implant through a radio frequency (RF) telemetry link from a distance of up to two feet. When it is not being used, the remote is in an idle (or sleep) mode from which it can be reactivated by any button press. During normal patient use, the device will transition to idle mode automatically after 60 sec-onds of non-use. Some remote functions (i.e., patient Options and Clinician Mode) are accessed via a “long button press” (press and hold for approximately three seconds). These are identified in the appropriate sections fol-lowing.Program ButtonArea ButtonStimulation On/Off ButtonUp/ActivateDown/Save
Patient Remote Control37Stimulation On/OffStimulation is turned on and off via a dedicated power switch on the Remote Control keypad. Simply press the stimulation on/off button at any time to change the stimulation status of the implant. Stimulation AmplitudeThe Level screen is the Remote Control’s “default” screen. The remote will automatically return to this screen within 15 seconds of any button activity.Note: When there is no button activity for more than 60 seconds, the Remote Control will transition to idle mode and the display screen will be blank.Press the S or T button from the Level screen to decrease or increase amplitude. The Level screen also displays a bar graphic in the upper right corner to indicate the battery charge level of the implant. Three filled-in bars represents a fully-charged battery. As the battery strength is reduced, depending on the patient’s stimulation settings and usage, the bars will “empty” accordingly. Patients are encouraged to recharge the implant at the first “Recharge Battery Soon” message displayed by the Remote Control.

After the remote times out to the Level screen, you may change the amplitude of all areas in the program, or you may adjust the Rate or Pulse Width of an individual area by navigating to the Options settings (see “Options” on page 40).4. To save/store changes, select the program again and press T. You will be required to confirm the adjustment first. 5. Press Dto confirm, or press the Cbutton to cancel the opera-tion.
40Physician Implant ManualNote: To save the modifications as a new program, simply select an empty (X) program slot and press Tinstead of overwriting the existing program.Options With the Precision SCS system, the Rate and Pulse Width parameters are generally considered programming “options” in that relatively few patients will actually use these settings. By default, Rate and Pulse Width are off-limits to the patient Remote Control unless you allow access using BionicNavigator software.Another option, “Restore,” is readily available to all patients. The Restore feature allows patients to return a program to the original set-tings you programmed for them at the initial fitting or at a follow-up. To Access the Rate and Pulse Width Options:1. Press and hold the Cbutton for three seconds (a long button press) or until the Rate Area 1 screen appears.2. As necessary, press the Cbutton normally to cycle to the area you wish to adjust.

To continue with a Pulse Width adjustment, press and hold the Area button from any Rate Area screen to navigate to Pulse Width Area 1. 5. As necessary, press the Cbutton normally to cycle to the area you wish to adjust. 6. When the desired area screen is displayed, press S or T to increase or decrease the Pulse Width.To Access the Restore Option1. Press and hold Dto reach Restore Program 1.2. If necessary, press the Dbutton again (normal press) to cycle through the programs and select the program to be restored.3. Press S to restore the last clinic-programmed settings..Device LinkingA Remote Control can communicate with only one stimulator at a time. This prevents the remote from accidentally controlling an unin-tended device. For this reason, the initial step in the linking process involves the Remote Control identifying, by telemetry, the intended
42Physician Implant Manualstimulator for communication.The second step in establishing the link depends on: • Whether the stimulator is an External Trial Stimulator (ETS) or an IPG;• Whether the Remote Control or the stimulator has stored programs or whether they are clear of programs;• Where a different program set is present in both devices, which set is to be cleared.An un-linked Remote Control will display the following message upon first activation (when any button is pressed) or immediately fol-lowing a de-linking action:
Patient Remote Control431. Press Dto initiate communication between the remote and the stimulator within telemetry range. The remote will identify the device by ID number. 2. Press Dto confirm and continue.The Precision system software will automatically detect whether the stimulator is a trial or a permanent device, and whether program sets are available and where. If both the Remote Control and the target stimulator are clear of programs, the link is completed immediately and you will see this message: However, if programs are present in either device during linking, you will be required to respond to one or more “decision” screens to guide the remote to complete the linking with the desired program set saved
44Physician Implant Manualto the desired device (remote or stimulator). You may also need to enter the clinician’s password. If an error occurs during the process or if the password is incorrect linking will be aborted. For further information, including informa-tion about the clinician’s password, see “To Clear Link” following. Clinician OptionsPatient-restricted clinician screens provide access to:• Remote Control and stimulator clearing and relinking• Communication with the clinician programmer • Electrode impedance monitoring To access clinician screens:1. Press the Cand Dbuttons simultaneously for approximately three seconds. The Enter Clinician Options screen will appear as shown below. 2. Press the appropriate button to select an option. Each option is discussed in sequence below.
Patient Remote Control45To Clear Link When the Dbutton is pressed from the Enter Clinician Options screen, you will immediately be required to enter the clinician’s pass-word in order to continue.To enter the password: The first character is highlighted when the Enter Password screen opens. To select/confirm any character and/or move to the next char-acter position, press D. To scroll through possible characters, use S or T.
46Physician Implant ManualWhen clearing a link: If the password is entered correctly, the link between the Remote Control and the “previous” stimulator is broken immediately , and the remote displays the Not Linked screen. The Remote Control’s programs remain intact. If the password is entered incorrectly, the process is aborted and the remote will return to the Enter Clinician Options screen. Note: If the password is entered incorrectly during an attempt to link the Remote Control, the process is aborted and the remote returns to the Idle screen.For CP Mode1. From the Enter Clinician Mode screen (See page 44), press the C button to prepare the Remote Control for communication with the Clinician’s Programmer (CP). Note: The remote will remain CP Ready for 15 minutes.
Patient Remote Control472. Place the remote and the IR dongle in the IR Holder with their communication ports facing.3. Plug the dongle’s USB connector into the slot in the CP and power-on the programmer.4. Launch the BionicNavigator software and wait for the IR Com-munication Established display.For ImpedancesWhen S is selected from the Enter Clinician Options screen, the Remote Control will take the measurements via telemetry; this will take a few seconds.
48Physician Implant ManualEventually, the remote will display the Electrode Impedance Sta-tus screen.Electrodes 1 through 8 (lead position 1-L) are represented by the rectangles in the top row; electrodes 9 through 16 (lead position 2-R) are represented by the rectangles in the bottom row. Electrodes within the acceptable impedance range are displayed as solid rectangles; high impedance electrodes (above 4500 ohms) are represented by hollow rectangles.Note: • The Remote Control will terminate the CP Ready state and transition to the idle mode if there is no IR signal after 15 minutes.•All buttons are active during CP Ready and pressing any button returns the Remote Control to the Level screen.•Stimulation may be turned on or off during CP Ready.•Once IR Communication is established, the Remote Control will terminate communication and transition to the idle mode if there is no IR activity after 15 minutes.•All buttons are active during IR Communication and press-ing any button returns the Remote Control to the Level screen.
Patient Remote Control49•Whenever the remote is re-activated from idle mode the dis-play will default to the Level screen.Programmer CommunicationThe Clinician Programmer can communicate with either an External Trial Stimulator or an IPG. In order to begin a programming session, the CP and the Remote Control IR windows must be aligned. Arrange for the patient to be seated within two feet of the Remote Control to ensure a complete communication link from the program-mer to the stimulator.For instructions on how to use the Clinician Programmer with the BionicNavigator software to program the IPG and transfer programs to the Remote Control, see the BionicNavigator Software Guide.
