First Claim
Patent Images
1. Apparatus for delivering a prosthesis into a target vessel of a patient, comprising:
- a flexible catheter having proximal and distal ends, said catheter comprising an outer sheath, a pusher shaft, and an inner shaft;
an expandable member coupled to the inner shaft;
a plurality of tubular prostheses releasably carried over the expandable member, the outer sheath disposed over the prostheses and being axially movable relative thereto, a distal end of the pusher shaft abutting a proximal end of one of the tubular prostheses; and
a garage member at the distal end of the outer sheath having sufficient radial strength to constrain a proximal portion of the expandable member within the garage member from expansion when a distal portion of the expandable member outside the garage member is expanded to deploy one of the tubular prostheses, the garage member having a length at least as long as one of the tubular prostheses.

Abstract
Apparatus for delivering stents to body lumens include one or more tubular prostheses carried at the distal end of a catheter shaft, a sheath slidably disposed over the prostheses, and a guidewire tube extending from within the sheath to the exterior of the sheath through an exit port in a sidewall thereof. A guidewire extends slidably through the guidewire tube. The sheath can be moved relative to the catheter shaft and the guidewire tube to expose the prostheses for deployment. Methods of delivering stents are also provided.
