1. An implantable sensor for detecting indicators of the density of a tissue in a body, comprising:
- a sensor having an external surface adapted to engage a portion of the body to maintain a position in the body, the sensor configured for detecting a signal indicative of a density of the tissue; and
a telemetry circuit in communication with the sensing element adapted for transmitting the detected signal outside of the tissue.

Abstract
An implantable sensor for detecting changes in tissue density is disclosed. The implantable sensor includes a transducer adapted for detecting indicators of tissue density. The implantable sensor includes memory for storing data corresponding to the tissue density indicators detected by the sensor. A telemetry circuit is configured for transmitting the tissue density data outside of the body.
