Pressure monitor catheter for use with monorail system.

摘要

A blood pressure monitoring catheter for use in a Monorail TM intravascular system for measuring the pressure gradient across a stenotic lesion. It comprises an elongated, flexible, plastic, extruded, tubular member (12) having a guidewire port (22) extending through the wall thereof a short distance proximal to the distal end of the tubular member to intersect with a lumen (18) which extends to the distal end. The second lumen (20) runs the entire length of the tubular member from its distal end to its proximal end. The proximal end of the blood pressure monitor catheter is fitted to a molded plastic hub (26) to facilitate the attachment of the catheter to the blood pressure measuring apparatus with which the catheter is to be used.
