Abstract: In a medical telemetry system for synchronizing an implantable medical device to a base station of the telemetry system, a communication channel is selected for communication between the implantable medical device and the base station, and the implantable medical device is synchronized to the base station by selecting a synchronizing word associated with the selected channel, wherein at least two different communication channels within the medical telemetry system are associated with different synchronization words. By this procedure, crosstalk is eliminated.

Abstract: An IMD has its communication circuitry in an inactive state and has access to two different identifier codes. The IMD activates the communication circuitry based on reception of a wakeup message that includes an identifier code that is identical to the identifier code currently assigned to the IMD. A communication device generates and transmits first wakeup messages that include a first identifier code associated with the IMD and second wakeup messages that include a second identifier code associated with the IMD. Depending on the currently assigned identifier code of the IMD the IMD will respond to either first or second wakeup messages.
