Implantable medical device with integrated antenna system
First Claim
1. 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.

Abstract
The present invention is related to active implantable medical devices comprising an antenna and a band diplexer connected to said antenna. The band diplexer comprises first filter means for a first signal to be transmitted and/or received in a first RF band and second filter means for a second signal to be transmitted and/or received in a second RF band. A method of bidirectional wireless communication is disclosed between an active implantable medical device and an external device, comprising the steps of: communicating unidirectionally from the external device to the implantable medical device over a first wireless link in a first RF band in the MI near-field and communicating unidirectionally from the implantable medical device to the external device over a second wireless link in a second RF band in the EM field.
