Abstract
A communication protocol that is configured to extend the battery life of devices that monitor and/or affect body parameters and is particularly useful in a system comprised of a system control unit (SCU) and one or more implanted devices. Each such implanted device is configured to be monitored and/or controlled by the SCU via a wireless communication channel. The time between battery rechargings is determined by the battery capacity and the device's power consumption. Accordingly, the present invention reduces their average power consumption by reducing the usage duty cycle of their power consuming transmit and receive modes used to communicate with the SCU. By dedicating addressable time slots to each of the implantable devices in the system and limiting their use of receive and transmit modes to time periods proximate to these time slots, the average power consumption is accordingly reduced.
