Patent ID: 8369959

Claim:
An implantable medical device having an implantable component configured to at least one of receive external data, generate internal data, and receive power signals, the device comprising: an implantable antenna for transmitting and receiving external radio frequency (RF) signals to and from one or more devices positionable external a patient's body; and a reciprocal frequency multiplexer-filter circuit configured to concurrently frequency-filter high- and low-frequency external RF signals received by said implantable antenna, and to concurrently frequency-multiplex common-mode high-frequency RF signals and differential-mode low-frequency RF signals to form high- and low-frequency external RF signals, respectively, for transmission to said one or more external devices via said implantable antenna, said common-mode high- and differential-mode low-frequency RF signals corresponding to said internal data generated by said implantable component.
