IMPLANTABLE PULSE GENERATOR SYSTEMS AND METHODS FOR PROVIDING FUNCTIONAL AND/OR THERAPEUTIC STIMULATION OF MUSCLES AND/OR NERVES AND/OR CENTRAL NERVOUS SYSTEM TISSUE

摘要

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.

1. An implantable pulse generator system comprising
a pulse generator comprising a housing sized and configured for implantation in subcutaneous tissue, circuitry carried within the housing and adapted for wireless telemetry, a rechargeable battery coupled to the circuitry and carried within the housing, the battery having a voltage, a power receiving coil carried within the housing and coupled to the circuitry, the power receiving coil for transcutaneously receiving an externally generated radio frequency magnetic field to recharge the rechargeable battery, an external controller including circuitry adapted for wireless telemetry, and a charging coil for generating the radio frequency magnetic field to transcutaneously recharge the rechargeable battery, and wherein during a battery recharge period, and 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.
