Abstract
A sensor for sensing blood pressure within an underlying artery as the underlying artery is compressed includes a transducer and a compressible sidewall. The transducer senses blood pressure of blood pressure pulses as the pulses travel beneath the sensor. As each blood pressure pulses crosses an edge of the sensor, each pulse exerts a force on the sensor in a direction parallel to the underlying artery. Tissue surrounding the underlying artery also exerts a force. The compressible sidewall is distant from the transducer and engages tissue surrounding the underlying artery. The compressible side wall neutralizes the force exerted by the tissue surrounding the underlying artery and dampens the force parallel to the underlying artery so that a substantially zero pressure gradient exists across the transducer.
