1. A system for monitoring an implantable medical device (IMD) within a body, comprising:
- a first circuit to receive an electrical signal that is representative of an acoustic signal existing within a body; and
a second circuit coupled to the first circuit to provide an audible signal from the received electrical signal for use in determining status associated with the IMD.

Abstract
The current invention provides an improved system for monitoring status of an IMD within a body. The system includes a device such as a lead, guidewire, stylet, catheter, or other IMD carrying a device such as a microphone for detecting acoustic signals in the body. The IMD is coupled to an amplifier device which generates an audible signal that may be utilized to determine status associated with the IMD, including location and tissue-contact data. A processing circuit may further be provided to aid in the analysis of the acoustic data.
