The implantable, electrically operated medical device system comprises an implantable radio frequency (RF) receiver and an external RF transmitter. The receiver has a receiving antenna and electronic circuitry coupled to the receiving antenna and includes a microcontroller having an output, a non-volatile memory coupled to the microcontroller and an implanted, electrically and autonomously operated medical device is coupled to the output of the microcontroller. The external RF transmitter has a power source and a transmitting antenna. The receiver further includes circuitry coupled to the microcontroller for regulating the power transmitted by the transmitter, whereby, RF energy can be transmitted by the transmitter and coupled into the receiver and the level of RF energy transmitted by the transmitter is controlled by the circuitry. The transmitter is also used to: a) program into the memory of the implanted device (receiver) its operating values; b) start and stop delivery of medical therapy by the implanted device, c) interrogate the operating values of the implanted device, and d) interrogate physiological parameters which are measured by the implanted device.
