Implantable pulse generator systems and methods for operating the same
First Claim
1. A method comprising:
- transcutaneously recharging a rechargeable battery within a housing of an implantable electrical stimulation generator via an externally generated radio frequency magnetic field, wherein the radio frequency magnetic field is generated via a first circuitry of an external controller and a charging coil coupled to the first circuitry, wherein the externally generated radio frequency magnetic field is received via a power receiving coil carried within the housing of the implantable electrical stimulation generator to recharge the rechargeable battery;
wirelessly communicating with an antenna and second circuitry of the implantable electrical stimulation generator via the first circuitry of the external controller using at least one of UHF signals or VHF signals, wherein transcutaneously recharging the rechargeable battery comprises transcutaneously recharging the rechargeable battery during a battery recharge period, wherein wirelessly communicating comprises wirelessly receiving, during the battery recharge period, status information from the implantable electrical stimulator to allow the external controller to automatically adjust the magnitude of the radio frequency magnetic field; and
automatically adjusting a magnitude of the radio frequency magnetic field based on the received status information.

Abstract
Improved assemblies, systems, and methods provide a stimulation system for prosthetic or therapeutic stimulation of muscles, nerves, or central nervous system tissue, or any combination. The stimulation system includes an implantable pulse generator and a lead sized and configured to be implanted subcutaneously in a tissue region. An external controller includes circuitry adapted for wireless telemetry and a charging coil for generating the radio frequency magnetic field to transcutaneously recharge a rechargeable battery in the pulse generator. Using wireless telemetry, the pulse generator is adapted to transmit status information back to the external controller to allow the external controller to automatically adjust up or down the magnitude of the radio frequency magnetic field and/or to instruct a user to reposition the charging coil, the status information adapted to allow optimal recharging of the pulse generator rechargeable battery.
