SENSOR IN CANNULA FOR VENTRICULAR ASSIST DEVICE. Characteristics of a pressure microsensor for automatic control of ventricular assist device (VAD) have been evaluated. The sensor consists of a pyrex glass cover and a silicon chip. This absolute pressure sensor has high stability because of the four resistors diffused into the diaphragm. The sensor is built in outflow cannula which is sustained with thin membrane of anti-thrombogenic material together with surface of cannula. After 60 days VAD

This result indicates the possibility of the clinical application of this pressure sensor in cannula for VAD.
