Patent ID: 8688224

Claim:
A combination comprising an implantable biomedical device and an electrical energy generator, wherein said electrical energy generator is capable of generating electrical energy from kinetic energy by electromagnetic induction, said electrical energy generator being in electrical connection with said implantable biomedical device, wherein said electrical energy generator comprises: a housing having a longitudinal axis, an interior cavity and an interior cavity surface, and an exterior surface; electrically conductive material positioned about at least a portion of said exterior surface of said housing and extending along at least a portion of said longitudinal axis of said housing; an electromagnetically active mass positioned within said housing reciprocally movable along at least a portion of said longitudinal axis of said housing; and guidance means to minimize or substantially prevent the non-reciprocating motion of said electromagnetically active mass within said housing, wherein said guidance means comprises a rod engaged with said housing and passing through said electromagnetically active mass.
