First Claim
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.

Abstract
An external transmitter inductive coil can be provided in, on, or with a belt designed to be placed externally around a part of a body of a patient. An implantable device (such as a VAD or other medical device) that is implanted within the patient'"'"'s body has associated with a receiver inductive coil that gets implanted within that part of the patient'"'"'s body along with the device. The externally-located transmitter inductive coil inductively transfers electromagnetic power into that part of the body and thus to the receiver inductive coil. The implanted receiver inductive coil thus wirelessly receives the inductively-transferred electromagnetic power, and operates the implant.
