Patent ID: 8840743

Claim:
A method of fabricating a balloon catheter, comprising: providing an inner tubular member having a distal section, a distal end, and a lumen extending therein; forming a balloon having a working length, a distal neck, and a distal leg, the distal leg having a first segment with a first diameter and first wall thickness and a second segment with a second diameter and second wall thickness, the second diameter being larger than the first diameter and the second wall thickness being thinner than the first wall thickness; positioning the distal end of the inner tubular member in the balloon, with the first segment of the distal leg disposed proximate the distal section of the inner tubular member and the second segment of the distal leg extending distally beyond the distal end of the inner tubular member; heating the distal leg of the balloon to bond at least a portion of the first segment to the distal section of the inner tubular member and to reduce the second diameter of the second segment of the distal leg.
