Apparatus for rejection diagnostics after organ transplants
First Claim
1. A transponder device for rejection diagnostics of a transplant, after organ transplantations, said transponder device comprisingan extracorporal base station (1) with a high frequency transmitter (2) which emits high frequency signals and a receiver unit (3), anda telemetric rejection sensor (6) implantable in a patient'"'"'s body, comprisinga high frequency receiver unit (9'"'"') for receiving the high frequency signals from the extracorporeal base station,a rectifier and decoder unit (18) for converting the high frequency signals received into a supply voltage and control records for the rejection sensor (6),an energy storage (19) for storing the supply voltage,a control unit (20) for controlling measuring processes within the rejection sensor,a sensor arrangement (12) controlled by the control unit (20) and adapted to be in contact with a transplant to be monitored and having a measuring electrode configuration for measuring rejection-specific measured variables,an encoder unit (29) for converting the measured variables furnished by the sensor arrangement (12) into corresponding data signals, as well asa high frequency emitter unit (31) for transmitting the data signals produced by the encoder unit (29) to the extracorporal base station (1).

Abstract
An apparatus for rejection diagnostics after organ transplantations is provided with
an extracorporal base station with a high frequency transmitter and receiver unit, and
a telemetric rejection sensor implantable in a patient'"'"'s body, comprising
a high frequency receiver unit for receiving high frequency signals from the base station,
a rectifier and decoder unit for converting the high frequency signals received into a supply voltage and control records for the rejection sensor,
an energy storage for storing the supply voltage,
a control unit for controlling the measuring processes within the apparatus,
a sensor arrangement controlled by the control unit and to be brought into contact with the organ to be monitored and having measuring electrodes for measuring rejection-specific variables,
an encoder unit for converting the measured variables into corresponding data signals, as well as
a high frequency emitter unit for transmitting the data signals produced by the encoder unit to the extracorporal base station.
