Abstract
Stent delivery systems including a deployment sheath for the stent, and an anti-catch member positionable adjacent to a proximal end of the deployment sheath and designed to allow the proximal end of the deployment sheath to be passed through the stent without catching on the stent.
Claims20
A stent delivery system, comprising:
- an inner member having a distal end region;
- a deployment sheath disposed along the distal end region of the inner member and defining a space between the inner member and the deployment sheath and configured to contain an entirety of a stent, the deployment sheath having a proximal end;
- the inner member and the deployment sheath being designed to slide distally relative to the stent disposed in the space between the inner member and the deployment sheath in order to deploy the stent;
- and
- an intermediate member disposed along the inner member and configured to extend within the stent when the stent is within the deployment sheath, the intermediate member including an anti-catch member, the intermediate member being movable relative to the deployment sheath such that the anti-catch member is positionable adjacent to the proximal end of the deployment sheath and designed to allow the proximal end of the deployment sheath to be passed through the stent without catching on the stent.

A stent delivery system, comprising:
- an inner member having a distal end region;
- a deployment sheath coupled to the inner member and disposed along the distal end region of the inner member, the deployment sheath having a proximal end;
- a stent disposed entirely within a space between the inner member and the deployment sheath;
- an intermediate member disposed along the inner member within the stent and including an anti-catch member;
- the inner member and the deployment sheath being designed to slide distally relative to the stent in order to deploy the stent;
- and
- the intermediate member including the anti-catch member being movable relative to the deployment sheath such that the anti-catch member includes a first position in which the anti-catch member is spaced from the proximal end of the deployment sheath and a second position in which the anti-catch member is positioned adjacent to the proximal end of the deployment sheath and is designed to allow the proximal end of the deployment sheath to be passed through the stent without catching on the stent.

A method of deploying a stent, the method comprising:
- delivering a stent delivery system into the anatomy of a patient, the stent delivery system including;
- an inner member having a distal end region;
- a deployment sheath disposed along the distal end region of the inner member, the deployment sheath having a proximal end;
- a stent disposed entirely within a space between the inner member and the deployment sheath;
- and
- an intermediate member disposed along the inner member within the stent and including an anti-catch member;
- deploying the stent by sliding the inner member and the deployment sheath distally relative to the stent;
- moving the anti-catch member relative to the deployment sheath such that the anti-catch member is positioned adjacent to the proximal end of the deployment sheath;
- and
- passing the deployment sheath through the stent, wherein the anti-catch member is designed to allow the proximal end of the deployment sheath to be passed through the stent without catching on the stent.
