  • Balloon catheter and stent deploying catheter system
    Patent number: 6383212
    Abstract: A balloon catheter with a balloon having first and second tapered sections adjacent the distal and proximal ends of the working length of the balloon, respectively, and third and fourth tapered sections adjacent the first and second tapered section, respectively. The first and second tapered sections taper at a first angle to a smaller outer diameter than the inflated outer diameter of the working length inflated within a deployment range of the balloon, and the third and fourth tapered sections taper at a second angle larger than the first angle. The balloon has expandable retention sections proximal and the distal to the working length of the balloon for inhibiting migration of a stent mounted on the balloon.
    Type: Grant
    Filed: December 11, 2000
    Date of Patent: May 7, 2002
    Assignee: Advanced Cardiovascular Systems, Inc.
