Abstract
Steerable balloon dilatation catheter assembly having dye injection and pressure measurement capabilities and comprising an elongate flexible tubular member having first and second lumens extending therethrough and a balloon carried by the distal portion of the tubular member and having its interior in communication with the second lumen. A guide wire extends through the first lumen and has a coil carried by the distal portion thereof and extending beyond the distal extremity of the tubular member. A device is coupled to the guide wire facilitating at least limited rotation of the distal extremity of the guide wire. A first fitting is coupled to the second lumen and is adapted to receive a liquid for inflating and deflating the balloon. A second fitting is in communication with the first lumen. The first lumen and the guide wire being sized so that dye injections and/or pressure measurements can be made through the second fitting.
