Abstract
A catheter assembly including a guide wire having a proximal end, a distal end, and a balloon catheter. The balloon catheter includes a tubular member having a balloon proximate the distal end, and a guide wire tube having a lumen therethrough for slidably receiving the guide wire. The guide wire tube extends longitudinally along the exterior surface of the balloon from a point proximate the distal end of the balloon past the proximal end of the balloon. The guide wire tube is elastic and collapses radially when pressed against a vessel wall during inflation of the balloon. In a preferred method of use, the guide wire is placed in a first position across a treatment area followed by threading the balloon catheter over the guide wire so that balloon is also across the treatment area. The guide wire is then pulled in a proximal direction to a second retracted position, wherein the distal end of the guide wire is proximal of the proximal end of the balloon, yet within the guide wire tube. The balloon is then inflated for treatment followed by deflation. The guide wire is then pushed in the distal direction back to the first position, wherein the guide wire is across the treatment area…
