Adjustable magnetic supercutaneous device & transcuteanous coupling apparatus

An externally worn body device adapted to be magnetically held in a supercutaneous position having a case (28), having a first surface adapted to be adjacent the supercutaneous position. A magnetic device (34) is attached to the case for magnetically holding the case (28) in the supercutaneous position. The magnetic device (34) is moveable with respect to the distance of the magnetic device from the first surface of the case thereby allowing for adjustability in magnetic field strength at the first surface of the case. The magnetic device (34) may be threadably attached to the case (28) for screwably allowing movement of the magnetic device with respect to the first surface of the case (28). Optionally, the magnetic device may be affixed to the case once suitable adjustment has been made. The externally worn body device may further include a transmitting device (30) positioned within the case (28) for transmitting an electrical signal intended for transcutaneous reception. The externally worn body device may be combined with an implanted subcutaneous member (26) which contains a magnetic device (24) for providing an appropriate magnetic attraction to the corresponding supercutaneous magnetic device. The subcutaneous member may contain a receiving coil (22) designed to cooperate with the transmitting coil (30) of the externally worn body device for the reception of transcutaneous electrical signals.
