Abstract
An external fluid-filled catheter pressure transducer for monitoring fluid pressure characteristics in a vessel in a living body. The external fluid-filled catheter pressure transducer includes an inverted sensor bonded to a hollow carrier so that measuring occurs on the inside of the carrier. The fluid-filled catheter pressure transducer allows pressure measurements to be taken in vessels smaller than 1 mm in diameter. A method for manufacturing an external fluid-filled catheter pressure transducer describes connecting sections of tubing (semi-rigid and flexible) to an inverted sensor module, and providing a reference port for the inverted sensor module.
