Abstract

An apparatus comprises a communication channel comprising a plurality of disparate sequential communication links configured to facilitate bi-direction communication between an implantable medical device (IMD) and a programmer. A transceiver is configured to communicate with the programmer via a first communication link of the plurality of disparate communication links. A telemetry device is configured to communicate with the IMD via a second communication link of the plurality of disparate communication links. A third communication link communicatively couples the transceiver and the telemetry device. A power source is coupled to the transceiver and to the telemetry apparatus. An operational status of at least the first and second communication links can be individually determined in real-time.
