Balloon catheter for multiple adjustable stent deployment
First Claim
Patent Images
1. A method of delivering a plurality of stents, comprising:
- intravascularly advancing a catheter proximate or adjacent to a first portion of a 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 portion of the lesion which is adjacent to the first portion; and
expanding the balloon to expand the second stent at the second portion of the lesion.

Abstract
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.

13. A method of delivering a plurality of stents, comprising:
-
intravascularly advancing a catheter proximate or adjacent to a first portion of a lesion, the catheter having a distal end, an inflatable balloon near the distal end, a first stent slidably positionable to surround the balloon, and a second stent proximal to the first stent; sliding the first stent into direct contact upon the balloon; separating the first stent from the second stent such that the second stent is proximal to the balloon; expanding the balloon to expand the first stent at the first portion of the lesion; sliding the second stent toward the distal end so that the second stent is positioned in direct contact upon the balloon; repositioning the catheter proximate or adjacent to a second portion of the lesion which is adjacent to the first portion; and expanding the balloon to expand the second stent at the second portion of the lesion. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
