Implantable Lead and Lead Introducer Kit, package contents, device specifications and the StimRouter implant procedure. Refer to the StimRouter User’s Guide for a full description of the StimRouter User Kit, StimRouter Electrode, External Pulse Transmitter (EPT), Patient Programmer, external accessories, package contents, device specifications and instructions for use.
The StimRouter Clinician Programmer and the patient-operated system consisting of the StimRouter Patient Programmer, StimRouter External Pulse Transmitter (EPT), and the StimRouter Electrode, should only be used under proper medical guidance and as described in the StimRouter Clinician’s Guide and in the StimRouter User’s Guide. Indications...
• Patients with bleeding disorders or active anticoagulation that cannot be stopped for a few days prior to the time of the surgical procedure. • Do not use the transmit/receive RF head coil if the StimRouter Lead is implanted above the shoulder. Implantation Setting The StimRouter Lead should be implanted in an appropriately outfitted physician’s...
Failure to follow all warnings and guidelines related to MRI can result in SERIOUS INJURY to the patient. • The implanted StimRouter Lead should not be within transmit RF body coil unless the specific restrictions are followed for reduced radiofrequency (RF) power deposition (i.e., WBA SAR or B...
Normal Operating Mode of operation for the MR system • Limit B1 and or SAR to values in Table 2.1 if the entire StimRouter is not at least 50 cm from the center of the MRI bore. (This is the Reduced RF Zone.)

Do not scan if StimRouter is inside the coil or less than a coil radius away from the edge. Using the Transmit/Receive RF Hand/Wrist Coil MRI scans with the Transmit/Receive RF Knee Coil may be performed provided that StimRouter Lead is outside the coil and at least one coil radius away from the edge of the coil.

StimRouter Lead is outside the coil and at least one coil radius away from the edge of the coil. Do not scan if StimRouter is inside the coil or less than a coil radius away from the edge.
Temperature changes of the StimRouter Lead electrodes were measured at 3 T/128 MHz according to ASTM International F2182 (i.e., using a 128-MHz transmit RF body coil). With the StimRouter 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...
MRI were calculated. If the StimRouter Lead is at least 50 cm from the center of the bore of the MR system and outside the gradient coils of the MR system, the induced current will be less than the stimulation threshold.
Advise patients to turn off the StimRouter system (Patient Programmer and stimulation) when near a refueling station, flammable fuel, fumes, or chemicals. The operation of the StimRouter could cause the chemicals or fumes to ignite, causing severe burns, injury, or death.
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.
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 StimRouter system and all other electronic devices. Refer to the Troubleshooting section for help and the Appendix for more information.
For Single Patient Use Only The StimRouter Electrode should 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.
Do not apply the StimRouter Electrode over skin folds, scarred tissue, irritated skin, uneven skin surfaces, or broken skin. • Always inspect the gel pads on the back of the StimRouter Electrode before use. Do not apply the StimRouter electrode if the gel pads appear dried out, worn, dirty, or irregular.
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).
Page 32
• 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 contact their physician.
1, 2, 3, 6, and 12 months after randomization. Safety The safety of the StimRouter System is based on all 94 patients implanted with a StimRouter Lead. Of the 94 subjects implanted with the StimRouter lead, none experienced unanticipated or serious adverse events related to the device or therapy.

Figure 10 -1: StimRouter Electrode and EPT connecting Adhering the StimRouter Electrode to the Skin WARNING: Do not touch the gel pads of the StimRouter Electrode with both hands while stimulation is turned on. Serious injury could result from electrical current passing across the chest cavity.
Page 72
The center of the gel pad should be above the receiver end of the lead. See Figure 10- 4. If the StimRouter electrode is not directly over the receiver end of the lead, then stimulation may be uncomfortable or ineffective.
Electrode is placed partially or wholly over a bandage or other obstruction, then skin irritation or tissue damage could occur during stimulation. 6. 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.

To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the StimRouter system is used exceeds the applicable RF compliance level above, the StimRouter system should be observed to verify normal operation.
