ABSTRACT:
An implantable subcutaneous data port for transferring data received from a sensor implanted within a subject. The data port electrically connects to the sensor and includes a control circuit electrically connected to an access port. The control circuit includes a current loop transmitter which modulates a current loop signal with voltage outputs from the sensor. This current loop signal transmits through the access port to an externally located current loop receiver which converts the current loop signal into an output voltage. Needle electrodes are insertable through the skin of the subject to the access port and provide an electrical interface between the control circuit and current loop receiver.
