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.
