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. An implantable medical device comprising a housing, circuitry carried within the housing for performing a predefined function, a power receiving coil carried within the housing and coupled to the circuitry, the power receiving coil for receiving externally generated power, the power receiving coil having a maximum outside dimension X, and wherein the implantable medical device is adapted to be implanted in subcutaneous tissue at an implant depth D, such that the ratio of X/D is between about 0.8 to 1 and about 4 to 1.

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 may include both external and internal components, with an implantable pulse generator sized and configured to be implanted subcutaneously in a tissue region. The implantable pulse generator includes a welded titanium case. Circuitry and hardware adapted for wireless telemetry is located within the case, and includes a primary cell or rechargeable power source, a microcontroller for control of the implantable pulse generator, and a power receiving coil for receiving an RF magnetic field to recharge the rechargeable power source, the power receiving coil having a maximum outside dimension.
