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.

Disclosed is a system to provide adaptive tuning through a control system to a finger cuff connectable to a patient's finger to be used in measuring the patient's blood pressure in the patient's artery by a blood pressure measurement system utilizing a volume clamp method. When the finger cuff is placed around the patient's finger, the bladder and the LED-PD pair aid in measuring the patient's blood pressure by the blood pressure measurement system utilizing the volume clamp method, wherein the adaptive tuning system: applies a first pressure impulse and measures a pleth versus time response; from the pressure versus time response, determines pleth servo gains that compensate for delays in a pleth response of the finger; and uses the determined pleth servo gains in the control system in measuring the patient's blood pressure by the blood pressure measurement system utilizing the volume clamp method.

Apparatus and methods for the measurement, control, or both, of thermodilution injectate flow for calculation of transpulmonary thermodilution parameters. An injectate delivery system includes a syringe for holding an injectate and a conduit configured at one end to be connected to a catheter. A flow measurement device is interposed in the conduit to generate a signal for determining the flow rate of the fluid from the syringe to the catheter. A processor receives the signal from the flow measurement device and calculates the injectate volume to be used as input for calculating a transpulmonary thermodilution parameter such as cardiac output. A GUI is provided to direct a user on whether the injection rate is too fast or too slow. Rather than measuring or calculating flow rate, a system may include a constant flow valve to provide a constant flow rate from the syringe.
