A stimulation system for prosthetic or therapeutic stimulation of muscles, nerves, or central nervous system tissue, is provided. The system includes external and internal components, with a hermetically sealed pulse generator and lead configured to be implanted in subcutaneous tissue, the lead extending up to an anatomical furthest distance from the pulse generator. The pulse generator includes circuitry and hardware adapted for non-inductive wireless telemetry using VHF/UHF signals located within a welded titanium case, the telemetry for transmitting status information, and includes a unique signature for secure communications. The pulse generator includes a primary or rechargeable battery, a microcontroller, and a power receiving coil for receiving power to recharge a rechargeable battery, the power receiving coil having a maximum outside dimension. The circuitry is adapted to suspend the generation of stimulation at a first remaining battery capacity, and to enter a dormant mode at a second remaining battery capacity. |
