Abstract:
A telemetry system for monitoring a rejection reaction of a transplanted organ being transplanted within a patient's body, the telemetry system comprising:(a) a telemetry control unit located outside the body of the patient; and(b) a telemetry monitoring unit implanted within the body of the patient, said telemetry monitoring unit including:(i) at least one acoustic transducer being for receiving an acoustic signal from said telemetry control unit and converting said acoustic signal into a first electrical signal, said at least one acoustic transducer further being for receiving a second electrical signal and converting said second electrical signal into a transmitted acoustic signal receivable by said telemetry monitoring unit; and(ii) a plurality of electrodes positionable in intimate contact with, or deep within, the transplanted organ and being in communication with said at least one acoustic transducer, said plurality of electrodes being for passing said first electrical signal through the transplanted organ for monitoring the electrical impedance thereof and further being for relaying said second electrical signal corresponding to said electrical impedance to said at least one acoustic transducer so as to enable the monitoring of the presence or absence of the rejection reaction.
