Information 1.5 T/64 MHz For situations where the entire StimRouter Lead is located outside of the Reduced RF Zone: Temperature changes of the electrodes of the StimRouter Lead were measured at 1.5 T/64 MHz according to American Society for Testing and Materials (ASTM) International F2182 (i.e., using a 64-MHz transmit RF body coil).
SAR of 2 W/kg predicts a worst-case heating of an implanted StimRouter Lead in the patient during an MRI exam of less than 2°C after 15 minutes of continuous scanning (i.e., per pulse sequence) provided that the entire StimRouter Lead implant is outside of the Reduced RF Zone (see Figures 2-1 to 2-6).
A computer simulation showed that there would be less than a 1°C heating of an implanted StimRouter Lead in the patient during an MRI exam, provided the entire StimRouter Lead implant was outside of the Reduced RF Zone (see Figures). The computer simulation incorporated the worst-case measured temperature rise at several anatomic locations and a whole-body-averaged (WAR) SAR of 2 W/kg.
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.
Electromagnetic Compatibility Warnings Medical Devices/Therapies Operation of the StimRouter system in close proximity (e.g., 1 meter) to shortwave or microwave therapy equipment may produce instability in the EPT output. The following medical therapies or procedures may turn stimulation off. They may also permanently damage the StimRouter external components and may cause injury, particularly if used close to the system components.
To minimize interference, maintain a minimum safe separation distance of 15 cm (6 in.) between the StimRouter system and all other electronic devices. See the “Troubleshooting” section for help. See the “Appendix”...
