Abstract
A method is presented for enabling radio-frequency (RF) communications between an implantable medical device and an external device in a manner which reduces the power requirements of the implantable device by duty cycling its RF circuitry. A wakeup scheme for the implantable device is provided in which the external device transmits a data segment containing a repeating sequence of special wakeup characters and a device ID in order to establish a communications session with the implantable device. The wakeup scheme may be designed to operate using multiple communications channels.
