FLEXIBLE GALVANIC PRIMARY & NON GALVANIC SECONDARY COILS FOR WIRELESS COPLANAR ENERGY TRANSFER (CET)

摘要

Systems and methods of the invention generally involve a convertible power transfer system for supplying wireless energy to an implant. According to certain aspect, a system of the invention includes a convertible inductive coil and a receiver inductive coil. The convertible inductive coil may be disposed externally on a body of a patient and to inductively transmit electromagnetic power. The convertible inductive coil transitions between direct electromagnetic power transfer and passive electromagnetic power transfer. The receiver inductive coil can be implanted within the body and provides received electromagnetic power to the implant. The convertible inductive coil, during passive electromagnetic power transfer, couples to the receiver inductive coil such that the convertible inductive coil and receiver inductive coil operate together as single receiver inductive coil that receives inductively transferred electromagnetic power from a distant transmitter inductive coil.

1. A system for wirelessly powering an implant, comprising:
a convertible inductive coil configured to be disposed externally on a body of a patient, to inductively transmit electromagnetic power, and to transition between direct power transfer and passive power transfer; and a receiver inductive coil configured to be implanted within the body and associated with the implant to wirelessly receive the inductively transferred power and provide that received power to the implant; the convertible inductive coil configured to, during passive power transfer, couple to the receiver inductive coil such that the convertible inductive coil and receiver inductive coil operate together as single receiver inductive coil that receives inductively transferred power from a distant transmitter inductive coil.
