Balloon catheter for multiple adjustable stent deployment
First Claim
Patent Images
1. A stent delivery system comprising:
- a catheter having a distal end and an inflatable balloon near the distal end for expanding a stent surrounding the balloon, the catheter carrying a plurality of stents, the catheter further carrying a separating mechanism which is non-releasable from a distal end of the catheter whereby a stent to be expanded is separated from an undeployed adjacent stent, and having a positioner slidable longitudinally along the catheter independently of said plurality of stents for moving said plurality of stents relative to said balloon from a first position proximal to the distal end to a second position closer to the distal end in which at least one of said plurality of stents surrounds the balloon.

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.

9. A stent delivery system comprising:
a catheter having a distal end and an inflatable balloon near the distal end for expanding a stent surrounding the balloon, the catheter carrying a plurality of stents, the catheter further carrying a separating mechanism which is non-releasable from a distal end of the catheter whereby a stent to be expanded is separated from an undeployed adjacent stent, and having a positioner slidable longitudinally along the catheter and adapted to engage only a proximal stent of said plurality of stents to move said plurality of stents relative to said balloon from a first position proximal to the distal end to a second position closer to the distal end in which at least one of said plurality of stents surrounds the balloon for deployment therefrom. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
