Abstract
Diagnostic apparatus (24) includes a sealed case (40), including a biocompatible material and configured for implantation within a body of a human subject (22). At least one antenna (42) is configured to be implanted in the body in proximity to a target tissue (28) and to receive radio frequency (RF) electromagnetic waves propagated through the target tissue and to output a signal in response to the received waves. Processing circuitry (44,46), which is contained within the case, us coupled to receive and process the signal from the antenna so as to derive and output an indication of a characteristic of the target tissue.

49. A diagnostic apparatus, comprising:
-
a sealed case, comprising a biocompatible material and configured for implantation within a body; a first antenna and a second antenna, each antenna 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; and processing circuitry, which is 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. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)

65. A diagnostic apparatus, comprising:
-
a sealed case, comprising a biocompatible material and configured for implantation within a body of a patient; a first antenna and a second antenna, each antenna configured to; be implanted in the body in proximity to a lung of the patient, 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; and processing circuitry, which is 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 measure of a change in a level of the fluid content in the lung of the patient; and at least one of a heart beat of the patient and a respiratory motion of the patient. - View Dependent Claims (66, 67, 68)
