Balloon catheter for multiple adjustable stent deployment

摘要

A catheter configured to carry one or more stents and having an inflatable balloon for expanding a stent surrounding the balloon. The catheter is characterized in having a positioner for moving the one or more stents relative to the balloon from a first position in which the stent does not surround the balloon to a second position in which the stent surrounds the balloon. Also disclosed is a method for deploying a stent at a desired location in the vascular system.

主权项

1. A method of delivering a plurality of stents, comprising:
intravascularly advancing a catheter proximate or adjacent to a first lesion, the catheter having a distal end, an inflatable balloon near the distal end, and at least a first stent and a second stent slidably positionable in direct contact upon the balloon; separating the first stent from the second stent such that the first stent is positioned upon the balloon; expanding the balloon to expand the first stent at the first lesion while the second stent is retained unexpanded on the catheter; repositioning the catheter proximate or adjacent to a second lesion; and expanding the balloon to expand the second stent at the second lesion, wherein the first stent and the second stent have different lengths.
