Abstract

An interface relay system for use with a fully implantable medical devices that permits transcutaneous coupling of the implanted medical device to a consumer electronics device. In one embodiment, coupling the implanted medical device to the external electronics device provides a back-up source of power for operating the implanted medical device. In another embodiment, coupling the implanted medical device to the external electronics device allows for providing unidirectional and/or bidirectional data transfer between the devices. In one arrangement, the consumer electronics device may be connectable to a communications/data network to allow for network communication between the implantable medical device and a remote processing platform/server.
