Abstract
A pressure gauge is described that can be encased in a small‐bore plastic cathether. The small size permits insertion directly into the heart. The unit uses a two‐section piezoresistive element, operated as a cantilever. The sensitivity of the gauge is 0.16 mv/v/psi, and the frequency response is flat from 0 to 400 cps.Keywords
