Claim Text:
1. A system for wirelessly powering an implantable ventricular assist device (VAD), comprising: a transmitter inductive coil configured to be disposed externally around a part of a body of a patient within which the VAD is implanted and to inductively transfer electromagnetic power into that part of the body; a receiver inductive coil associated with the VAD and configured to be implanted within that part of the patient's body along with the VAD to wirelessly receive the inductively-transferred electromagnetic power and provide that received power to the VAD; and a DC-to-DC converter configured to be implanted within the patient's body along with the receiver inductive coil and the VAD, wherein the DC-to-DC converter automatically adjusts to provide a substantially constant and optimum load to the receiver inductive coil.
