Implantable pulse generator systems and methods for providing functional and/or therapeutic stimulation of muscles and/or nerves and/or central nervous system tissue
First Claim
1. A pulse generator adapted to be coupled to an electrode to provide electrical stimulation comprising:
- a housing configured for implantation in tissue of a patienta rechargeable battery carried within the housing;
circuitry carried within the housing and coupled to the rechargeable battery, the circuitry comprising first circuitry for generating electrical stimulation pulses and second circuitry for recharging the rechargeable battery; and
a power receiving coil coupled to the second circuitry,wherein the circuitry is configured to suspend the generation of electrical stimulation pulses when a capacity of the rechargeable battery decreases below a first remaining capacity and the circuitry is configured to cause the pulse generator to enter a dormant mode when the capacity of the rechargeable battery decreases below a second remaining capacity,wherein the first and second circuitry are electrically isolated from the rechargeable battery when the pulse generator is in the dormant mode,wherein the pulse generator is configured to exit the dormant mode upon receipt of power by the power receiving coil from a transcutaneously applied radio frequency magnetic field,wherein the pulse generator exits the dormant mode by at least electrically reconnecting the second circuitry to the rechargeable battery, andwherein the second remaining capacity comprises a safety margin capacity between approximately 5% and approximately 20% of a total capacity of the battery.

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 a pulse generator including a housing sized and configured for implantation in subcutaneous tissue, circuitry carried within the housing, the circuitry operable for generating electrical stimulation pulses, and a rechargeable battery coupled to the circuitry and carried within the housing, the rechargeable battery including a battery capacity. The circuitry is adapted to suspend the generation of electrical stimulation pulses at a first remaining battery capacity, and the circuitry is adapted to enter a dormant mode at a second remaining battery capacity. The first battery remaining capacity may be greater than or equal to the second remaining battery capacity. At the second remaining battery capacity, only a safety margin battery capacity remains.
