Abstract
An implantable medical device includes an acoustic transducer for intra-body communication with another medical device via an acoustic couple. The acoustic transducer includes one or more piezoelectric transducers. In one embodiment, an implantable medical device housing contains a cardiac rhythm management (CRM) device and an acoustic communication circuit. The acoustic communication circuit includes an error detection circuit configured for detecting an error rate associated with demodulated incoming acoustic signals and a frequency selection circuit configured for adjusting a carrier frequency of outbound acoustic signals. The acoustic transducer is electrically connected to the acoustic communication circuit to function as an acoustic coupler and physically fastened to a wall of the implantable housing, directly or via a supporting structure.
