Abstract
A signal reading and charging device for use with an implantable telemetric medical sensor comprises a casing and a circuit within the casing comprising a logic control unit and a processing unit. The logic control unit sends a powering signal to the telemetric medical sensor for remotely powering the sensor. The logic control unit also receives a transmitted signal from the sensor. The processing unit is operatively connected to the control unit for converting the transmitted signal by the sensor into a measured parameter. An antenna coil is used for sending the powering signal and receiving the transmitted signal from the sensor. The device also includes a display for displaying the measured parameter.
