Implantable pulse generator power management
First Claim
1. A neuromuscular stimulation system comprising:
- at least one electrode; and
an implantable pulse generator that includes a rechargeable power source and a power receiving coil coupled to the rechargeable power source, wherein the power receiving coil is configured to transcutaneously receive power from an externally generated radio frequency magnetic field to recharge the rechargeable power source,wherein the implantable pulse generator is configured to deliver electrical stimulation via the at least one electrode,wherein the implantable pulse generator comprises first circuitry configured to generate the electrical stimulation, second circuitry configured for wireless telemetry, and third circuitry for recharging the rechargeable power source, andwherein the implantable pulse generator is configured to operate in an active and charging mode, an active mode, and a dormant mode,wherein, when in the active and charging mode, the implantable pulse generator provides power from the rechargeable power source to the first and second circuitry of the implantable pulse generator and receives power from the externally generated radio frequency magnetic field via the power receiving coil to recharge the rechargeable power source,wherein, when in the active mode, the implantable pulse generator provides power from the rechargeable power source to the first and second circuitry of the implantable pulse generator and does not receive power from the externally generated radio frequency magnetic field to recharge the rechargeable power source, andwherein, when the implantable pulse generator is in the dormant mode, the rechargeable power source is electrically isolated from the first circuitry, the second circuitry, and the third circuitry of the implantable pulse generator, and wherein the implantable pulse generator is configured to enter the dormant mode when a predetermined capacity of the rechargeable power source has been discharged.

Abstract
Improved assemblies, systems, and methods provide an implantable pulse generator for prosthetic or therapeutic stimulation of muscles, nerves, or central nervous system tissue, or any combination thereof. The implantable pulse generator is sized and configured to be implanted subcutaneously in a tissue region. The implantable pulse generator includes an electrically conductive case of a laser welded titanium material. Control circuitry is located within the case. The control circuitry includes a rechargeable power source, a receive coil for receiving an RF magnetic field to recharge the power source, and a microcontroller for control of the implantable pulse generator. The improved assemblies, systems, and methods also provide a stimulation system for prosthetic or therapeutic stimulation of muscles, nerves, or central nervous system tissue, or any combination thereof. The stimulation system provides at least one electrically conductive surface, a lead connected to the electrically conductive surface, and an implantable pulse generator electrically connected to the lead.
