Timing coordination of implantable medical sensor modules
First Claim
1. An implantable medical device comprising:
- a host controller configured to transmit a signal over a two-wire bus; and
a plurality of sensor modules that are each coupled directly to each wire of the two wire bus to receive the signal from the bus, wherein a timing coordination for performance of sensor actions by each of the plurality of sensor modules is based on the received signal in order to make a measurement, wherein each of the plurality of sensor modules includes one or more light emitters and one or more light detectors, and wherein the plurality of sensor modules are each configured to simultaneously receive power from the two-wire bus.

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.
