Abstract

An electronic implantable device with a power saving circuit incorporates a radio frequency receiver with high power consumption. The first power radio receiver of high power is normally turned off during a period of inactivity. When an analyzer forming part of a second radio receiver and coupled to the first radio receiver detects a predetermined identification code in a received radio frequency signal received by the second radio receiver, it outputs a signal to turn on the first power receiver.
