Chapter 1 - Introduction 1
2 Clinician’s Guide
2 Warnings and Cautions Clinicians and patients should know the limitations, warnings and precautions associated with the StimRouter Neuromodulation System. Clinicians should review the warnings and precautions and instructions for use with the patient. If at any time the clinician or patient is concerned about the safety or effectiveness of the StimRouter system, then call your local distributor. The StimRouter programming system and patient-operated system should only be used under proper medical guidance and as described in this StimRouter Clinician’s Guide and in the StimRouter User’s Guide. Indications for Use The Bioness StimRouter Neuromodulation System is intended to provide electrical stimulation via an implanted lead to a target peripheral nerve, for aid in the management of adults that have severe intractable chronic pain of peripheral nerve origin, as an adjunct to other modes of therapy (e.g. medications). The StimRouter is not intended to treat pain in the craniofacial region. Contraindications The Bioness StimRouter Neuromodulation System is contraindicated for: • Patients who have any active implanted device such as an implanted demand cardiac pacemaker or defibrillator, or any metallic implant in the immediate area intended for implant. Maintain a minimum safe separation distance of 15 cm (6 in.) between the SimRouter system and all other active implanted devices and metallic implants. A risk/benefit determination should be performed before using the StimRouter system for: • Patients exposed to diathermy. Shortwave, microwave and/or therapeutic ultrasound diathermy should not be used on patients who have a StimRouter Neuromodulation System. The energy generated by diathermy can be transferred through the StimRouter system components, causing tissue damage at the lead site and potentially resulting in severe injury. Diathermy may also damage the StimRouter system components, resulting in loss of therapy. Injury or damage can occur during diathermy treatment Chapter 2 - Warnings and Cautions 3
whether neurostimulation is turned on or off. All patients are advised to inform their health-care professionals that they should not be exposed to diathermy. Patients exposed to therapeutic ultrasound. Patients who are unable to operate the StimRouter system. Patient who are high surgical risks or poor surgical candidates in general. Patients who have a cancerous lesion present near the target stimulation point or near to where the StimRouter electrode will adhere. Patients who are known or suspected to have a nickel allergy. The handles of the tunneling needle and tunneling needle stylet are nickel plated. Patients with bleeding disorders or active anticoagulation that cannot be stopped for a few days close to the time of the surgical procedure. • • • • • • Implantation Setting The StimRouter should be implanted in an appropriately outfitted physician office, outpatient surgical center or hospital surgical center. Fluoroscopy and/or ultrasound should be available if deemed necessary and be used at the implanting physician’s discretion. Patient Screening Candidates for StimRouter therapy should be appropriately screened for selection and fully informed about the therapy risks and benefits, the surgical procedure, system operation and self-treatment responsibilities. Select patients carefully to ensure that: • • • Their symptoms are of an anatomical and/or physiological origin. They are appropriate candidates for surgery. They can properly operate the StimRouter system. Bioness highly recommends the following screening procedure prior to StimRouter lead implantation: • • Nerve block using local anesthesia. Psychological screening using techniques traditionally used for similar types of procedures and systems. 4 Clinician’s Guide
Bioness recommends the following optional screening procedure prior to StimRouter lead implantation: • Transcutaneous electrical nerve stimulation (TENS) to determine the patient’s tolerance of stimulation near the anticipated site for the StimRouter electrode. Please note that some individuals are very sensitive to the sensation to electrical stimulation applied to the skin. Warnings Magnetic Resonance Imaging MRI Warnings and Precautions • Do not scan patients with a specific absorption rate (SAR) level exceeding 2 W/kg. A scan above 2 W/kg may increase the risk of MR-related heating. Do not place a local RF transmit coil directly over the Bioness implanted lead. The entire Bioness implanted lead must always be outside the MR coil and must not be exposed to any radio frequency field. • • StimRouter External Component Restrictions All external components of the StimRouter system are contraindicated for the MRI environment. Therefore, the StimRouter electrode, external pulse transmitter and patient programmer must be removed before the patient is allowed into the MRI environment. Chapter 2 - Warnings and Cautions 5
MRI Information Non-clinical testing has demonstrated that the StimRouter lead is MR Conditional. Patients with an implanted StimRouter lead can be scanned safely, immediately after implantation, on MRI cylindrical bore systems that meet the following conditions: • • • Static magnetic field of 1.5 Tesla (T) or 3 T. Highest spatial magnetic gradient of 2500 gauss/cm or less. MR system reported, whole-body-averaged SAR does not exceed 2 W/kg at 1.5 T and 2 W/kg at 3 T. Do not scan patients with a SAR level exceeding 2 W/kg. A scan above 2 W/kg may increase the risk of MR-related heating. The entire StimRouter lead must be at least 50 cm from the center of the MR system’s bore (the iso-center of the bore) and at least 16 cm outside of the MR coil measured from the edge of the MR coil, to ensure patient safety relative to MRI-related heating. See Figure 2-1. • • Bore Table RF Coil Isocenter >50 cm cm >16 >16 cm Lead Lead Figure 2-1. The entire StimRouter lead must be at least 50 cm from the center of the MR system’s bore (the iso-center) and at least 16 cm outside of the MR coil measured from the edge of the MR coil. Left: lead implanted in the forearm. Right: Lead implanted in the lower leg. 6 Clinician’s Guide cm >50
• Communication is maintained with the patient so that the scan can be promptly terminated in the event of painful nerve stimulation or other adverse event. Information regarding the position of the lead is necessary for routine MRI procedures. Review of the patient’s Medical Device Identification Card, direct communication with the implanting physician or obtaining an x-ray is recommended to determine the location of the implanted lead. Patients must be screened for previously implanted (active or abandoned) medical devices, leads, lead extenders or lead adapters. MRI-Related Heating: Supplemental Information 1.5 T/64 MHz Temperature changes of the electrodes of the StimRouter lead were measured at 1.5 T/64 MHz according to ASTM F2182 (GE Signa, 46- 258170G1, whole body transmit radio frequency (RF) coil). With the lead in an orientation and a position in the phantom to produce worst-case heating, the greatest measured temperature rise scaled to a background local SAR of 1 W/kg was 3.9°C after six minutes of RF power application. This temperature change was with the lead in an elongated, “straight” configuration (i.e., no curves), which produced the highest temperature change. With the lead in curved or looped configurations, temperature changes were less. A computer simulation that incorporated the worst-case measured rise and a whole-body-averaged SAR of 2 W/kg predicts a worst case in the patient during MRI of less than 2°C provided that the entire StimRouter lead is at least 50 cm from the center of the bore of the MR system and at least 16 cm outside of the MR coil measured from the edge of the MR coil. 3 T/128 MHz Temperature changes of the electrodes of the StimRouter lead were measured at 3 T/128 MHz according to ASTM F2182 (GE Signa, 3T HDx, Software Version 15/LX/MR, 15.0.M4.0910a). With the lead in an orientation and a position in the phantom to produce worst-case heating, the greatest measured temperature rise scaled to a local background SAR of 2 W/kg was 2.9°C after six minutes of RF power application. This temperature change was with the lead in an elongated, “straight” configuration (i.e., no curves), which produced the highest temperature change. With the lead in curved or looped configurations, temperature changes were less. A computer simulation that incorporated the worst-case measured rise and a whole-body-averaged SAR of 2 W/kg predicts a worst case in the patient during MRI of less than 1°C provided that the entire StimRouter lead is at least 50 cm from the center of the bore of the MR system and at least 16 cm outside of the MR coil measured from the edge of the MR coil. Chapter 2 - Warnings and Cautions 7
Image Artifacts MR image quality may be compromised if the area of interest is in the exact same area or relatively close to the position of the StimRouter lead. Therefore, optimization of MR imaging parameters to compensate for the presence of the StimRouter lead may be necessary. Induced Currents The electric fields induced in the patient with the StimRouter lead by the pulsed gradient fields were calculated. The induced current will be less than the stimulation threshold if the StimRouter lead is at least 50 cm from the center of the bore and at least 16 cm outside of the MR coil measured from the edge of the MR coil. Potential Adverse Events Use of MRI could result in excessive heating of the lead if the MRI conditions of use are not followed. Induced voltages in the lead may occur, possibly causing uncomfortable levels of neurostimulation. Note: The StimRouter lead is not a life-sustaining device and could be explanted prior to an MRI procedure. Pregnancy The effects of electrical stimulation on pregnancy are unknown. Patients should avoid exposure to electrical stimulation for the entire duration of pregnancy. Long-Term Effectiveness of Neurostimulation The long-term effectiveness of neurostimulation is unknown. Programming The StimRouter components should only be programmed by the treating clinician and/or under proper medical guidance. 8 Clinician’s Guide
Device Components The use of non-Bioness components with the StimRouter system may result in damage to the system and increased risk to the patient. Flammable Fuel or Chemicals Advise patients to turn the StimRouter system (patient programmer and stimulation) off when near a refueling point, flammable fuel, fumes or chemicals. The operation of the StimRouter could cause the chemicals or fumes to ignite, causing severe burns, injury or death. Driving and Operating Machinery StimRouter stimulation should be off while driving and operating machinery. Electromagnetic Compatibility Warnings Medical Devices/Therapies The following medical therapies or procedures may turn stimulation off, may cause permanent damage to the external components and may injure the patient, particularly if used in close proximity to the system components: • • • • • • Lithotripsy Electrocautery External defibrillation Ultrasonic scanning High-output ultrasound Electromagnetic interference (EMI) from the following medical procedures is unlikely to affect the StimRouter system: Computerized Axial Tomography (CT or CAT) scans Diagnostic ultrasound (e.g., carotid scan, Doppler studies) Diagnostic x-rays or fluoroscopy • • • Note: Advise patients to remove the StimRouter electrode before undergoing medical therapies or procedures. Chapter 2 - Warnings and Cautions 9
Electrosurgery Devices Electrosurgery devices should not be used in close proximity to an implanted StimRouter lead. Contact between an active electrode of the electrosurgery device and the implanted lead can cause direct stimulation of the target stimulation point and severe injury to the patient. High-Frequency Surgical Equipment Simultaneous connection of a patient to the StimRouter components and high-frequency surgical equipment may result in skin burns where the gel electrodes adhere to the skin and may damage the StimRouter EPT. Advise patients to remove the StimRouter electrode before medical treatment. Body-Worn Devices Although unlikely, body-worn medical devices may interfere with the RF communication used in the StimRouter system. Stimulation control may be delayed. Examples of a body-worn device are an insulin pump and a monitoring device. The patient programmer will emit visual alerts if interference occurs. To minimize interference, maintain a minimum safe separation distance of 15 cm (6 in.) between the SimRouter system and all other electronic devices. See the Troubleshooting section for help. See the Appendix for more information. The StimRouter system wireless technology may cause EMI to other body- worn medical devices. Refer to the instructions for use for those devices for information on recommended minimum separation distances. Security Screening Devices Certain types of security devices may affect stimulation. Examples include those used at the entrances and exits of public buildings such as libraries, airports and retail stores. Ask for help to bypass the device. Show your Medical Device Identification Card. If you must pass through the device: • • • Turn off your StimRouter system. Pass through the device quickly. Stay as far from the emitter as possible. Walk, for example, in the center of a pass- through security gate. 10 Clinician’s Guide
Cell Phones There is potential for interference between electronic devices, including cell phones. Stimulation control may be delayed. If interference is suspected or anticipated, distance yourself from the source of interference. To minimize interference, maintain a minimum safe separation distance of 15 cm (6 in.) between the StimRouter system and all other electronic devices. Precautions Clinician Training Bioness requires that clinicians involved with the use of the StimRouter system be formally trained by Bioness in the system’s operation and use. Post-Operative Care Clinicians should adequately observe the incision site and monitor for infection, possible device rejection or other possible adverse effects. If the patient notices excessive redness or discharge around the incision site, then the implant physician should be contacted immediately to check for infection and administer proper treatment following standard medical procedures. Implant Location Advise patients to never manipulate the StimRouter lead. If the lead is moved from the target stimulation point, then it may not function correctly or effectively. In some instances a lead can move from its original location, thus causing a loss of stimulation at the target stimulation point. If the lead moves, then the lead may need to be replaced. For Single Patient Use Only The StimRouter electrode is meant to be worn only by the patient for whom it is prescribed and in the location for which it is prescribed. The StimRouter electrode should not be adhered to any other person or any other place on the patient’s body. Postural Changes Changes in posture or abrupt movements may decrease or increase the perceived level of stimulation. Advise patients to turn off stimulation before making extreme posture changes or abrupt movements such as stretching, lifting of arms overhead or exercising. Chapter 2 - Warnings and Cautions 11
Keep out of Reach of Children The StimRouter components should be kept out of the reach of children. Skin Abnormalities Do not adhere the StimRouter electrode to sites that are swollen, infected or inflamed, or that have skin eruptions such as phlebitis, thrombophlebitis and varicose veins. Do not adhere the StimRouter electrode to skin that is breached. Skin Irritation It is normal for the skin under the StimRouter electrode to become red. The redness should disappear in approximately one hour once the user patch is removed. However, some patients may experience skin irritation, an allergic reaction, or hypersensitivity to the electrical stimulation or the gel electrodes. Persistent redness, lesions or blisters are signs of irritation. Use of the StimRouter components should be temporarily halted until the irritation is resolved. In some cases, irritation can be avoided by removing the StimRouter electrode periodically to allow the skin to breathe and changing the stimulation parameters. Patients should consult their clinician if irritation persists. Known or Suspected Heart Problems Use caution when treating patients with suspected or diagnosed heart problems. StimRouter Electrode Placement and Stimulation • Electrical stimulation should not be applied trans-thoracically or at the heart such that current may travel into or through the cardiac tissue, as such introduction of electrical current may cause heart rhythm disturbances. Turn off stimulation before adhering, removing or handling the StimRouter electrode. StimRouter electrode placement and stimulation settings should be determined by the implanting physician and/or treating clinician. Do not apply the StimRouter electrode over any obstruction that would reduce the designated electrode surface area (for example, an adhesive bandage). A smaller electrode surface area could result in serious injury to the patient. Do not apply the StimRouter electrode over skin folds, scarred tissue, irritated skin, uneven skin surfaces or broken skin. • • • • 12 Clinician’s Guide
• Always inspect the gel electrodes before use. Do not apply the StimRouter electrode if the gel electrodes appear dried out, worn, dirty or irregular. Make sure the gel electrode liners are removed before applying the user patch. Do not handle the StimRouter electrode with both hands while stimulation is on; serious injury can result from current passing through the cardiac tissues. • • Expiration Date Do not use a StimRouter electrode with a “Use by” date that has expired. Implant Failure Leads may fail at any time because of random component failure or lead breakage. If component failure or lead breakage occurs, then the lead may need to be replaced. Storage and Handling All StimRouter components and accessories should be handled with care. Components and accessories should not be dropped. Although reliability testing has been performed to ensure quality manufacturing and performance, dropping the components on hard surfaces, or other rough handling, can permanently damage the components. Refer to the HP product literature included in the Clinician Kit for storage temperatures for the Hewlett Packard iPAQ 210 Enterprise Handheld. Tester Storage Temperature Range: -20°C to +60°C. Adverse Effects In the unlikely event that any of the following occurs, patients should stop using their StimRouter components, remove the StimRouter electrode and immediately consult their clinician or their implant physician. Risks Related to the Implant Procedure Suboptimal lead placement may necessitate therapeutic adjustment and/or lead explant. Nerve injury is possible, although unlikely. Possible surgical complications include infection, cellulitis, abscess, fever, sepsis, bleeding and temporary pain at the implant site. Chapter 2 - Warnings and Cautions 13
Risks Related to Stimulation • Operation of the StimRouter components may cause increased pain in an area other than the lead site. This pain may be caused by stimulation of the tissue surrounding the stimulation electrodes (e.g., skin, fascia and muscle). Patients may also experience an undesirable motor response during stimulation. • If patients experience any pain or discomfort during stimulation, or notice any skin abnormalities, they should stop stimulation immediately, remove the StimRouter electrode and contact their clinician. Additional Risks Related to the StimRouter System • • • Migration of the lead may cause changes in stimulation effectiveness. While very unlikely, a tissue reaction to any of the implanted materials may occur. External electromagnetic interference may cause the StimRouter components to malfunction and may affect stimulation. Patients may experience persistent pain at the implant site of the lead. Although rare, the skin overlying the lead may erode. Portable and mobile radio frequency communications equipment can affect medical electrical equipment. The StimRouter external components could overheat if the components fail, which could cause burning. • • • • If patients experience any pain or discomfort during stimulation, or notice any skin abnormalities, they should stop stimulation immediately, cease contact with the StimRouter components and notify their clinician. 14 Clinician’s Guide
3 Environmental Conditions that Affect Use Storage and Handling All StimRouter components should be kept dry and protected from extreme changes in temperature and humidity. Do not use or store components where they could come in contact with water, such as by sinks, bathtubs and shower stalls. Do not expose components to weather conditions such as rain or snow, or to any other source of water. Do not store StimRouter components in a car or elsewhere where hot or cold temperatures could exceed the acceptable ranges of the components. Temperature extremes can damage the StimRouter components. To avoid condensation when transporting StimRouter components from hot to cold temperatures, place the components in an air-tight plastic bag first. Let them adjust slowly (for at least two hours) to the change in temperature before use. Radio Communication Information Several components of the StimRouter system communicate via radio communication and have been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 (Radio Frequency Devices) of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential environment. This equipment generates, uses and can radiate radio frequency energy and, if not operated and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular environment. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, then try to correct the interference by one or more of the following measures: • • • Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Consult the dealer or an experienced radio/television technician for assistance. Chapter 3 - Environmental Conditions that Affect Use 15
The antenna for each transmitter must not be located near to or operating in conjunction with any other antenna or transmitter. Changes or modifications to components not expressly approved by Bioness could void the user’s authority to operate the equipment. Conformity Certification The StimRouter complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. 2. This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation. 16 Clinician’s Guide

4. Insert the patient programmer into the configuration cradle. Connecting the StimRouter Electrode and EPT To connect the StimRouter electrode and EPT: 1. Obtain an operational StimRouter electrode. Electrodes can be reused for as long as the gel electrodes can fully adhere to the skin. Do not remove the the reusable StimRouter electrode liner from the gel electrodes at this time. Set the StimRouter electrode on a flat surface with the gel electrodes facing down. Snap the EPT into the StimRouter electrode. See Figure 6-6. 2. 3. 4. Figure 6-6. StimRouter electrode and EPT connection. Note: To ensure proper electrical stimulation, the EPT must be connected to the StimRouter electrode properly. If the EPT does not work properly, then remove it from the StimRouter electrode and reconnect it, or connect it to a new electrode. Chapter 6 - Set-Up Instructions 37 EPT StimRouter Electrode
Adhering the StimRouter Electrode to the Skin The StimRouter electrode with EPT attached should be placed on the skin directly over the receiver end of the lead. For optimal stimulation, the skin where the StimRouter electrode will adhere should be clean and dry. This section describes how to prepare the skin, and how to adhere and remove the StimRouter electrode. Note: Transfer the EPT to a new StimRouter electrode when the gel electrodes adherence to the skin decreases.. To prepare the skin: 1. 2. Locate the area where the receiver end of the lead is implanted. Clean the skin above the receiver end of the lead with an alcohol swab or wet washcloth, and then dry. If the area has been treated with lotions or oils, then clean the skin with soap and water until all oils are removed, rinse well and dry. If necessary, remove excess body hair from the skin area using scissors. Do not use a razor. A razor can irritate the skin. 3. WARNING: Do not touch the gel electrodes with both hands while stimulation is turned on. Serious injury could result from electrical current passing across the chest cavity. Stimulation should be turned off before adhering, removing or handling the StimRouter electrode. WARNING: Do not apply the StimRouter electrode to anyone else or any other part of the body than that determined by the prescribing physician. The StimRouter electrode is for single patient use. 38 Clinician’s Guide
To adhere the StimRouter electrode: 1. 2. Remove the reusable StimRouter electrode liner and store it in the StimRouter electrode carrying case. The StimRouter electrode liner is larger than the electrode and is marked with the Bioness logo. See Figure 6- 8. Do not bend, break or soil the StimRouter electrode liner. Figure 6-8. Remove the StimRouter electrode liner. 3. Visually inspect the gel electrodes. Make sure the gel is smooth and attached to the StimRouter electrode. The gel should align with the contour of the StimRouter electrode and completely cover the base of the StimRouter electrode. Make sure the gel electrodes are not dry. Chapter 6 - Set-Up Instructions 39 Protective Covers
4. Using the index finger and thumb, grasp the edges of the StimRouter electrode so that the gel electrodes face away from the palm. See Figure 6-9. Figure 6-9. Grasp the edges of the EPT attached to the StimRouter electrode. 5. Align one end of the StimRouter electrode with EPT attached directly over the receiver end of the lead. If the StimRouter electrode is not directly over the receiver end of the lead, then stimulation may be uncomfortable or ineffective. See Figure 6-10. The effectiveness of the stimulation is sensitive to the alignment and rotation of the StimRouter electrode in relation to the receiver end of the lead. If the alignment or rotation of the StimRouter electrode changes, the stimulation intensity may need to be adjusted. Position the other end of the StimRouter electrode where it will minimize discomfort and avoid muscle contractions. 6. CAUTION: Do not pinch or stretch the skin while adhering the StimRouter electrode. EPT Electrode Figure 6-10. Optimal stimulation, position of the StimRouter electrode. (Illustration not to scale.) 40 Clinician’s Guide StimRouter Skin Lead Receiver End of Lead EPT
CAUTION: Make certain the adhesion site is free of obstructions (for example, bandages, clothing, etc.) before adhering the StimRouter electrode. If the StimRouter electrode is placed partially or wholly over a bandage or other obstruction, then skin irritation or tissue damage could occur during stimulation. 7. Firmly adhere the StimRouter electrode to the skin, making sure that the electrode is in full contact with the skin. If the StimRouter electrode is not firmly adhered to the skin and moves, then stimulation may become uncomfortable or ineffective. 8. Make certain that the patient programmer is within 10 feet of the StimRouter electrode (with EPT attached). Confirming Set-Up If the clinician programmer, patient programmer, EPT are connected correctly, the clinician programmer information icon will be GREEN, confirming online mode. To confirm the clinician programmer is in online mode: 1. 2. Check that the information icon on the clinician programmer is GREEN. If the information icon is not GREEN, make certain that the StimRouter electrode with the EPT attached is within 10 feet of the patient programmer. If the information icon is still not GREEN, check all connections and charge the patient programmer and the EPT. Test the EPT using the tester. See the “Troubleshooting” section of this guide. 3. 4. 5. 6. Refer to the StimRouter User’s Guide for additional operational instructions for the StimRouter patient programmer, EPT and StimRouter electrode, including instructions on how to: • • • • • Turn on the patient programmer. Charge the patient programmer. Adjust the volume of audio alerts on the patient programmer. Select a stimulation program using the patient programmer. Turn stimulation on using the patient programmer. Chapter 6 - Set-Up Instructions 41
• • • Adjust stimulation intensity using the patient programmer. Save a new stimulation intensity level on the patient programmer. Turn stimulation off using the patient programmer. Removing the StimRouter Electrode from the Skin/Body It may be necessary during set up to remove the StimRouter electrode to reposition it or test the EPT. To remove the StimRouter electrode: 1. To remove the StimRouter electrode, make certain that stimulation is turned off. Then grasp the tab on the StimRouter electrode and gently pull away from the skin. See Figure 6-13. Figure 6-13. Removing the StimRouter electrode. 2. Obtain a StimRouter electrode liner to protect the gel electrodes from drying out. Attach the liner to the gel electrodes. Store the StimRouter electrode with the liner attached in the StimRouter electrode carrying case. 3. 42 Clinician’s Guide StimRouter Electrode Tab
Testing the EPT The tester is used to test the functionality of an EPT. Before connecting the EPT to the tester, make sure the EPT is charged. Using the patient programmer or clinician programmer, stimulation can be turned on. Using the tester: 1. Connect the Tester snaps to the EPT plug holes. See Figure 6-14. Figure 6-14. Connecting the tester to the EPT. 2. 3. Press the patient programmer on/off button to turn on the system.

11 Troubleshooting The tables at the end of this section describe the visual indicators that may appear on the clinician programmer and patient programmer, and possible solutions for troubleshooting. In addition, this section describes solutions for the following scenarios that may arise during a programming session: • • • • The patient forgets to bring the patient programmer. The patient forgets to bring or has lost the EPT. The patient brings a new patient programmer and EPT. The patient forgets the StimRouter electrode. Patient Forgets Patient Programmer If a patient forgets to bring his or her patient programmer to a follow-up session, an alternate “clinic” patient programmer can be used. The clinic patient programmer must be reset and then registered to the patient’s EPT to proceed. Once the clinic patient programmer and patient’s EPT are registered, patient data stored on the EPT can be retrieved by the clinician programmer and new data can be stored on the EPT. The patient will need to re-register his or her EPT and patient programmer later. The new data stored on the EPT will overwrite the data stored on the patient programmer. Note: The information stored on an EPT will always overwrite the information stored on a patient programmer. Chapter 11 - Troubleshooting 73
Using a Clinic Patient Programmer To use a clinic patient programmer: 1. 2. 3. Connect the clinic patient programmer to the clinician programmer cradle. Make sure the EPT and the patient programmer are charged (if not, connect them to a charger). Make sure the patient programmer and the EPT are no more than a few inches apart and not touching. From the TOOLS MENU, press “Reset Patient Programmer/EPT.” Select “Reset the Patient Programmer” and press “Reset.” The StimRouter application will detect the unregistered patient programmer and ask whether you want to register this patient programmer to an EPT now. See Figure 11-1. 4. 5. 6. Figure 11-1. Unregistered patient programmer detected. 7. 8. 9. Press “Yes.” Once the patient programmer and EPT are registered, press “OK.” 10. From the Patient List, press “Open” to open the patient’s record. 74 Clinician’s Guide
Note: The patient Usage Log is stored on the EPT and is automatically retrieved when the patient programmer and EPT are connected. 11. Proceed with the programming session. Programming changes will be automatically saved to the EPT. 12. Before the session ends, remind the patient to re-register his or her EPT and patient programmer at home. Review with the patient the following instructions for RF registration. Registering the Patient Programmer/EPT The patient programmer and EPT must be electronically registered to each other to operate. To register the patient programmer/EPT: 1. 2. If necessary, charge the patient programmer. Ensure that the patient programmer is turned off (the on/off button should not be FLASHING GREEN). See Table 11-1. Table 11-1. Patient programmer on/off indicators. 3. 4. Make sure the EPT is charged (if not, connect the EPT to a charger). Place the patient programmer and the EPT close together on a table. Make sure the patient programmer and the EPT are no more than a few inches apart and not touching. Make certain that any other EPT is at least 10 feet away from the components to be registered. Simultaneously press and hold for three seconds the mode and minus buttons on the patient programmer to start the registration process. See Figure 11-2. The patient programmer will sound an audio alert, indicating the registration process has begun. The patient programmer digital display should show two ALTERNATING GREEN ARCHES, indicating registration is in progress. 5. 6. 7. Chapter 11 - Troubleshooting 75 Patient Programmer OFF Patient Programmer ON Flashing Green
On/Off Button Mode Button Volume Buttons Plus/Minus Buttons Unregistered In Process Complete Error Figure 11-2. StimRouter Patient Programmer operating buttons and RF registration status indicators. 8. When the digital display shows the letter “C” and the RF icon turns GREEN for a few seconds, the registration procedure is complete. Note: If the digital display shows the letter “E” and the RF icon turns RED for a few seconds, then an error has occurred and the procedure must be repeated. If the problem persists, reconnect the charger to the EPT. If the error indication continues to appear, see Table 11-7. Patient Forgets EPT If a patient forgets to bring his or her EPT to a follow-up session, reschedule the programming session. Do not substitute a clinic EPT for the patient’s EPT; only the patient programmer can be substituted. The information stored on an EPT will always overwrite the information stored on a patient programmer. If a clinic EPT is used, then the patient’s EPT will overwrite any new information stored on the patient programmer. 76 Clinician’s Guide
Patient Loses EPT When a patient loses an EPT, he or she will need to electronically register the patient programmer and new EPT. See “Registering the Patient Programmer/EPT” section of this guide. All data stored on the patient programmer will copy to the new EPT. However, since the usage history is stored on the EPT, any usage history that was not copied to the clinician programmer database is lost with the lost EPT. Patient Brings New EPT and New Patient Programmer If a patient receives a replacement EPT and patient programmer, then the patient will need to return to the clinic. The patient data stored on the clinician programmer database must be copied to the new EPT and patient programmer. Copying Patient Data to New Components To copy patient data to new components: 1. Connect the patient programmer to the clinician programmer and the configuration cradle. Make sure the patient’s EPT and the patient programmer are charged (if not, connect them to a charger). Make sure the patient programmer and the EPT are no more than a few inches apart and not touching. The StimRouter application will detect the unregistered patient programmer and ask whether you want to register this patient programmer to an EPT now. Press “Yes.” Once the patient programmer and EPT are registered, press “OK.” From the Patient List, select the patient’s record and press “Open.” Once the patient record is opened, all patient data except for history will copy to the patient’s new patient programmer and EPT. 2. 3. 4. 5. 6. 7. 8.

NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies. NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
