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 method of manufacturing a hermetically sealed implantable pulse generator comprising providing a top case and a bottom case and a header, coupling at least one feed-thru to the top case or the bottom case, or both, the at least one feed-thru including a feed-thru conductor having two ends, positioning circuitry in-between the top case and the bottom case, the circuitry adapted to be enclosed between the top case and the bottom case, coupling one end of the feed-thru conductor to the circuitry positioned in-between the top case and the bottom case, subjecting the top case and bottom case and the circuitry positioned in-between to a vacuum bake-out process, backfilling the top case and bottom case and the circuitry positioned in-between with an inert gas or inert gas mixture, laser welding the top case to the bottom case to create a hermetic seal, coupling the other end of the feed-thru conductor to the header, and coupling the header to the laser welded top case and bottom case.

13. A hermetically sealed implantable pulse generator comprising
a top case and a bottom case and a header, at least one feed-thru coupled to the top case or the bottom case, or both, the at least one feed-thru including a feed-thru conductor having two ends, circuitry positioned in-between the top case and the bottom case operable for generating electrical stimulation pulses, with one end of the feed-thru conductor coupled to the circuitry positioned in-between the top case and the bottom case, wherein the top case and bottom case and the circuitry positioned in-between are subjected to a vacuum bake-out process, and the top case and bottom case and the circuitry positioned in-between are backfilled with an inert gas or inert gas mixture, and the top case and bottom case are welded together to create a hermetic seal, and the other end of the feed-thru conductor is coupled to the header after the top case and bottom case are welded together.

25. A method of programming a hermetically sealed implantable pulse generator comprising
providing a hermetically sealed implantable pulse generator, the implantable pulse generator provided with or without application software necessary to control the sequencing and stimulus parameters of the implantable pulse generator for a predefined physiologic condition, using wireless telemetry, programming the implantable pulse generator with the desired application software adapted to control the sequencing and stimulus parameters of the implantable pulse generator for a predefined physiologic condition.
