First Claim
1. A system for wirelessly powering a ventricular assist device (VAD) implanted within a body of a patient, comprising:
- a receiver inductive coil associated with the VAD and configured to be disposed in the pleural cavity of the patient'"'"'s body to wirelessly receive inductively-transferred electromagnetic power and provide that received power to the VAD; and
a transmitter inductive coil comprising one or more turns of electrically-conductive material that are configured to surround the pleural cavity by being disposed externally and completely around a part of the patient'"'"'s body within which the pleural cavity is located, the transmitter inductive coil configured to inductively transfer electromagnetic power 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.

11. A system for wirelessly powering a ventricular assist device (VAD) implanted within a body of a patient, comprising:
-
a receiver inductive coil associated with the VAD and configured to be disposed in a left pleural cavity of the patient'"'"'s body to wirelessly receive inductively-transferred electromagnetic power and provide that received power to the VAD; a second receiver inductive coil associated with the VAD and configured to be disposed in a right pleural cavity of the patient'"'"'s body to wirelessly receive the inductively-transferred electromagnetic power and provide that received power to the VAD; and a transmitter inductive coil comprising one or more turns of electrically-conductive material that are configured to surround the left and right pleural cavities by being disposed externally and completely around a part of the patient'"'"'s body within which the left and right pleural cavities are located, the transmitter inductive coil configured to inductively transfer electromagnetic power to the receiver inductive coils. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
