Abstract
Diagnostic apparatus (24) includes a sealed case (80), comprising a biocompatible material and configured for implantation within a body of a human subject (22). A dielectrometric probe (26, 50, 63, 66, 70, 102, 160) is connected to the case and includes first and second conductors (40, 42, 54, 56, 64, 67, 68, 72, 74, 162, 164), which are configured to be placed in proximity to a target tissue (34) in the body. A driving circuit (82), which is contained in the case, is coupled to apply a radio-frequency (RF) signal to the probe and to sense the signal returned from the probe. Processing circuitry (84) is configured to evaluate, responsively to the returned signal, a dielectric property of the target tissue.
