Abstract
Abstract An implant device which includes a structure implantable within a living animal and a sensor included as part of the structure. The sensor is operatively configured to detect accretion of biological material on the sensor by producing an output which varies as a function of the accretion of biological material on the sensor. A communication element is further included as part of the structure and is operatively coupled to the output of the sensor. The communication element is configured to communicate information based on the output of the sensor wirelessly to a remote element located outside the living animal.
