<p>A sensor (180) having a sensing surface (100) for sensing blood pressure within an underlying artery of a patient includes a transducer (96), a sidewall (184), a flexible diaphragm (186) and a fluid coupling medium (188). The sidewall (184) is distinct from transducer (96) and supports the transducer (96) above the underlying artery. The fluid coupling medium (188) is coupled between the sensing surface (100) of transducer (96) and the flexible diaphragm (186) and transmits blood pressure pulses within the underlying artery from the flexible diaphragm (186) to the sensing surface (100) of transducer (96). In one embodiment, the fluid coupling medium (188) is isolated from sidewall (184).</p> |
