WIRELESS IMPLANT POWERING VIA SUBCUTANEOUS POWER RELAY
First Claim
Patent Images
1. A power relay device comprising:
- a housing configured to be disposed inside of a biological body;
a receiver disposed in the housing and configured to receive first power wirelessly from a power source disposed outside of the biological body while the receiver is disposed inside the biological body; and
a power conversion and transmission circuit disposed in the housing, operably coupled to the receiver, and configured to convert the first power into second power and to transmit the second power to an implant disposed in the biological body, the second power having a substantially different frequency than the first power, or being of a different type of power than the first power, or both.

Abstract
A method of providing power to an implant includes: transcutaneously receiving first power wirelessly from a source transmitter by a receiver of a power relay device, the receiver of the power relay device being disposed inside a biological body and closer to a skin of the biological body than the implant is to the skin of the biological body; converting the first power into second power that has a substantially different frequency than the first power, or is of different type of power than the first power, or both; and internally coupling the second power from a transmitter of the power relay device to the implant disposed within the biological body.

9. A power relay device comprising:
-
receiving means for receiving first power wirelessly from a power source disposed outside of a biological body while the receiving means are disposed inside the biological body proximate to an interior surface of the biological body; and converting and transmitting means, operably coupled to the receiving means, for converting power received by the receiving means into second power and transmitting the second power, the second power having a substantially different frequency than the first power, or being of a different type of power than the first power, or both. - View Dependent Claims (10, 11, 12, 13, 14)
