An implantable medical device ('IMD') as described herein includes an adjustable data retransmission scheme, which controls the manner in which data is retransmitted by the IMD. The retransmission feature can be adjusted in a dynamic manner based upon the type, context, or meaning of the telemetry data transmitted by the IMD. The IMD may process contextual meaning information that influences its data retransmission configuration. Such adjustability enables the IMD to satisfy minimum telemetry requirements in a manner that does not waste power, thus extending the IMD battery life.

Implantable medical device with variable data retransmission characteristics based upon data type

In general, channel occupancy techniques for multi-channel medical device communication are provided. More specifically, techniques are described for maintaining a communication session between an external device and an implantable medical device (IMD) to reduce the potential for conflict with other programmers. A device, such as an external device, includes a transmit module to transmit telemetry signals to an implantable medical device over a communication channel, and a control unit that communicates data to the IMD via the transmit module. The control unit communicates idle messages over the communication channel during gaps within the data communication to the IMD.
