Abstract
A sensor having a sensing surface for sensing blood pressure within an underlying artery of a patient includes a transducer, a sidewall, a flexible diaphragm and a fluid coupling medium. The sidewall is distinct from transducer and supports the transducer above the underlying artery. The fluid coupling medium is coupled between the sensing surface of transducer and the flexible diaphragm and transmits blood pressure pulses within the underlying artery from the flexible diaphragm to the sensing surface of transducer. In one embodiment, the fluid coupling medium is isolated from sidewall.
