Abstract
A repeater device allows a remote unit to control, program and/or monitor a medical implant device from a much further distance than has heretofore been possible. Such repeater device also facilitates transmitting other signals, i.e., other than control signals, to the medical implant device, such as, e.g., streaming audio, or other auxiliary input data. In one embodiment, the repeater device also allows status signals or sensed data originating within the medical implant device to be transmitted from the medical implant device through the repeater device to the remote unit, even though the remote unit may be located some distance, e.g., up to 200 feet, from the medical implant device. Such transmitted signals when received at the remote unit may be processed, analyzed, stored, monitored and/or displayed.
