Stent Delivery System Permitting in Vivo Stent Repositioning
First Claim
1. A stent delivery system for repositioning an improperly deployed stent in situ, the system comprising:
- a recapture component movable between a collapsed configuration and an expanded configuration;
an expandable stent mounted over the recapture component, wherein the stent remains connected to the recapture component after deployment such that when the recapture component is moved to the collapsed configuration the stent is at least partially contracted.

Abstract
A stent delivery system is disclosed that includes a recapture component for at least partially collapsing an improperly deployed stent in situ to permit repositioning and re-deployment of the stent. The recapture component and the stent may be disconnected in situ to allow for removal of the stent delivery system. In one embodiment, the recapture component is a balloon having loops or hooks around a periphery thereof for receiving at least one removable tether that couples the balloon and stent together. In another embodiment, the recapture component is an expandable tubular component connected to the stent via the removable tether.

17. A stent delivery system for repositioning a deployed stent in situ comprising:
-
an inflatable balloon, wherein the inflatable balloon includes a plurality of loops defining a plurality of lumens on an outside surface of the balloon; a deployable stent mounted over the inflatable balloon; and at least one removable tether woven between the loop lumens and the stent to connect the balloon and the stent in such a manner that the stent, after deployment, at least partially collapses when the balloon is deflated.

18. A method of repositioning a deployed stent in situ, the method comprising the steps of:
-
deploying a stent within a body lumen with a stent delivery system, the system having a recapture component connected to the stent and movable between a collapsed configuration and an expanded configuration; at least partially collapsing the recapture component to the collapsed configuration, thereby at least partially collapsing the stent; repositioning the stent within the body lumen; redeploying the stent within the body lumen with the stent delivery system; disconnecting the redeployed stent from the recapture component; and removing the stent delivery system from the body lumen. - View Dependent Claims (19, 20)
