Abstract
A diagnostic apparatus comprising a sealed case, a first antenna and a second antenna and processing circuitry are disclosed herein. In some embodiments, the sealed case includes a biocompatible material and is configured for implantation within a body of a patient. Further, each one of the first antenna and the second antenna are configured to be implanted in the body in proximity to a target tissue, generate and transmit radio frequency (RF) electromagnetic waves through the target tissue to the other antenna, and output a signal in response to RF waves received from the other antenna. In addition, the processing circuitry can be contained within the case and is configured to receive and process the signal from each antenna so as to derive and output an indication of a characteristic of the target tissue.
