1. A prosthetic valve comprising:
- a plurality of valve leaflets;
a frame assembly configured to support the plurality of valve leaflets, the frame assembly comprising an outer frame defining arcuate commissure regions and a flexible band comprising commissure support portions configured to fit at least partially within the arcuate commissure regions of the outer frame, the valve leaflets being secured at least in part between the outer frame and the flexible band;
a strain gauge device including one or more conductors applied directly to an outer surface of one of the commissure support portions of the flexible band, the strain gauge device being configured to generate a sensor signal providing a direct measurement of radial deflection of the one of the commissure support portions; and
a transmitter assembly configured to receive the sensor signal from the strain gauge device and wirelessly transmit a transmission signal, wherein the transmission signal is based at least in part on the sensor signal.

Abstract
Sensor-integrated prosthetic valves that can comprise a variety of features, including a plurality of valve leaflets, a frame assembly configured to support the plurality of valve leaflets and define a plurality of commissure supports terminating at an outflow end of the prosthetic valve, a sensor device associated with the frame assembly and configured to generate a sensor signal, for example, a sensor signal indicating deflection of one or more of the plurality of commissure supports, and a transmitter assembly configured to receive the sensor signal from the sensor device and wirelessly transmit a transmission signal that is based at least in part on the sensor signal.
