Abstract
A method for waking up an implantable medical device from a dormant state, an implantable medical device, and a system that includes such an implantable medical device and an external device. The implantable medical device is woken up from a dormant state by sending a modulated wakeup signal via a wireless link from an external device. The modulated wakeup signal is demodulated by way of a demodulator circuitry of the implantable medical device so as to produce a demodulated wakeup signal. The demodulator circuitry is permanently ready for operation. An awake state of the implantable medical device is then activated in response to the demodulated wakeup signal.
