Abstract
A telemetric medical system comprises a telemetric medical sensor for implantation in a patient's body for measuring a parameter therein. The sensor comprises a housing and a membrane at one end of the housing. The membrane is deformable in response to the parameter. A microchip is positioned within the housing and operatively communicates with the membrane for transmitting a signal indicative of the parameter. The system also includes a signal reading and charging device locatable outside of a patient's body for communication with the sensor. The signal reading and charging device comprises a casing and a circuit within the casing. The circuit includes a logic control unit and a processing unit. The logic control unit sends a powering signal to the sensor for remotely powering the sensor. The logic control unit also receives the transmitted signal from the sensor wherein the processing unit operatively connected to the control unit converts the transmitted signal by the sensor into a measured parameter.
