A Fabry-Pérot pressure sensor fabricated on left ventricular assist device for heart failure implant

An implantable Fabry-Pérot interferometer based pressure sensor is developed. The pressure sensor could be integrated directly onto the inlet shell of a left ventricular assist device (LVAD) to monitor blood pressure in real-time and provide a feedback control signal to achieve the optimal operation of LVAD. The diaphragm of the pressure sensor is made out of biocompatible polymer parylene-C.
