ABSTRACT:
An angioplasty balloon catheter having a balloon carried at the distal end of a catheter shaft. The catheter shaft includes an inflation lumen by which the balloon is inflated and deflated. A guide wire passage extends through the balloon. A guide wire assembly extends through the catheter shaft, through guide wire passage, and out the distal end of the balloon. The guide wire assembly carries, near its distal end, a selectively radially expandable valve which is used to limit or block fluid flow between the shaft lumen and the patient's body during inflation and deflation of the balloon.
