First Claim
1. A system for wirelessly powering a ventricular assist device (VAD) implanted within a body of a patient, comprising:
- a transmitter inductive coil configured to be disposed external to a part of the body of the patient, the transmitter inductive coil configured to inductively transfer electromagnetic power into that part of the body; and
a receiver inductive coil associated with the VAD and configured to be implanted within that part of the patient'"'"'s body to wirelessly receive the inductively-transferred electromagnetic power from the transmitter inductive coil and provide that received power to the VAD.

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.

- 28. A transmitter inductive coil configured to be disposed external to a part of a body of a patient within which a wirelessly-powerable implantable medical device is implanted and to inductively transfer electromagnetic power into that part of the body, the implantable medical device including a receiver inductive coil associated therewith and the implantable medical device together with the associated receiver inductive coil configured to be implanted within that part of the patient'"'"'s body to allow the implanted receiver inductive coil to wirelessly receive the inductively-transferred electromagnetic power from the transmitter inductive coil and provide that received power to the implanted implantable medical device.

- 36. A receiver inductive coil associated with a wirelessly-powerable implantable medical device and configured to be implanted within a part of a body of a patient along with the implantable medical device to wirelessly receive inductively-transferred electromagnetic power from external to the part of the patient'"'"'s body and provide that received power to the implanted implantable medical device, the inductively-transferred electromagnetic power being transmitted by a transmitter inductive coil configured to be disposed external to the part of the patient'"'"'s body within which the implantable device and its associated receiver inductive coil are implanted.
