Abstract
A pressure sensor assembly is disclosed which includes a flaccid tube having two mounting sleeve members that bond the tube to a distal end of a catheter. The catheter includes an aperture located beneath the tube and in communication with an air passage. As the pressure outside the tube changes, the tube moves relative to the catheter body, thereby communicating that pressure change to the sealed air passage within the catheter. This air passage is connected to an external transducer that can measure this pressure change and thereby determine a pressure at the distal end of the pressure catheter.
