Abstract:
In general, the disclosure is directed toward an implantable medical device that includes a plurality of sensor modules that are implanted within a patient. The sensor modules may cooperate with each other to coordinate the timing for performance of one or more sensor actions across the modules when making a measurement. Example measurements include tissue perfusion measurements, oxygen sensing measurements, sonomicrometry measurements, and pressure measurements. The coordination of the sensor modules may be controlled by a signal that is transmitted from a host controller to the sensor modules via a bus. In some examples, the bus may have two wires that transmit both timing information and data information to the sensor modules. The signal may be a signal that is substantially periodic, such as a pulsed signal. In additional examples, the signal may supply operating power and timing information to the sensor modules.
