An apparatus and method is presented for an implanted sound sensor wirelessly communicating with an implantable medical device, or with an external monitoring device. The second sensor may be located inside a blood vessel anchored by an expandable stent like device, and may be drug coated. The sound sensor may be a solid-state microphone having a unidirectional characteristic and may be aimed at a selected portion of the heart, lung, or other location. There may be a network of sound sensors forming a local area network with the implantable medical device. The information from the sound sensor may be analyzed, filtered, transformed, compared to a standard and stored in the implantable device, or it may be passed on to an external location. The results of the analysis may be use to initiate a closed-loop treatment by the implantable medical device, such as cardiac pacing or defibrillation.
