APPARATUS FOR CONTACTLESS POWER TRANSFER FOR IMPLANTABLE MEDICAL DEVICE

摘要

A transcutaneous recharging system for providing power to an implantable medical device comprises a primary side circuit for transmitting power in the form of magnetic flux; and a secondary side circuit integral to the implantable medical device for receiving the power transmitted from the primary side circuit and for providing the received power to recharge a battery in the implantable medical device, wherein the primary and secondary side circuits are not physically coupled. A variety of attachment configurations are disclosed for attaching and shielding the secondary circuit directly onto the housing of the implantable medical device, inclusive of flexible printed circuit coils and wire coils recessed into helical notches.
