1. An implantable power supply apparatus for supplying electrical energy to an electrically powered device, comprising:
- a power supply unit including;
A. a transcutaneously, invasively rechargeable non-electrical energy storage device (NESD);
B. an electrical energy storage device (EESD); and
C. an energy converter coupling said NESD and said EESD, said converter including means for converting non-electrical energy stored in said NESD to electrical energy and for transferring said electrical energy to said EESD, thereby storing said electrical energy in said EESD.

Abstract
The invention provides an implantable apparatus which includes a power supply capable of converting non-electrical energy such as mechanical, chemical, thermal, or nuclear energy into electrical energy. The invention also provides a method of supplying energy to an electrical device within a mammalian body in which the mammal is implanted with an apparatus including a power supply capable of converting non-electrical energy into electrical energy, and non-electrical energy is transcutaneously applied to the apparatus.
