SHORT WIRE STENT DELIVERY SYSTEM WITH SPLITTABLE OUTER SHEATH
First Claim
1. A delivery system for delivering a self-expanding prosthesis to a target location within a bodily lumen of a patient comprising:
- an elongate inner member extending between a distal end and a proximal end, the inner member comprising a passageway extending through at least a portion thereof between a distal opening disposed near the distal end and a proximal opening spaced proximally from the distal opening, the passageway comprising a coupling region for coupling to a guiding member;
an elongate outer member slidably disposed about the inner member, the outer member comprising an opening in communication with the proximal opening of the inner member; and
a self-expanding prosthesis disposed about the inner member and within the outer member;
wherein the prosthesis is deployable from the delivery system by proximal movement of the outer member relative to the inner member; and
wherein a guiding member disposed within the passageway of the inner member is laterally separatable from the inner member by proximal movement of the outer member relative to the inner member to thereby create an open channel for the guiding member to exit therefrom.

Abstract
A delivery system and method for introducing a self-expanding prosthesis into a work site of a patient. The delivery system is introduced to the work site over an elongate guiding member. The delivery system is subsequently uncoupled from the guiding member upon deployment of the prosthesis while remaining within the work site. In an exemplary embodiment of the invention, the delivery system comprises an elongate outer member slidably disposed about an elongate inner member. A self-expanding prosthesis is disposed within the outer member and is laterally constrained thereby in a compressed delivery configuration, and is constrained against longitudinal movement relative to the inner member. The inner member further comprises a passageway extending through the distal portion thereof the passageway extending between a distal opening near the distal end of the inner member and a proximal opening spaced proximally from the distal end of the inner member. The outer member comprises an opening in communication with the proximal opening of the inner member. The inner and outer members are configured to allow a guiding member disposed through the passageway and openings to pass laterally out of the passageway and openings upon proximal movement of the outer member relative to the inner member and deployment of the prosthesis.

20. A method of a self-expanding prosthesis to a target location within a bodily lumen of a patient comprising:
-
providing a prosthesis delivery system comprising an elongate outer member slidably disposed about an elongate inner member, and further comprising a self-expanding prosthesis disposed about the inner member and within the outer member, the inner member comprising a passageway extending through at least a portion thereof between a distal opening and a proximal opening spaced proximally from the distal opening, the outer member comprising an opening in communication with the proximal opening of the inner member; advancing the prosthesis delivery system along a guiding member, the guiding member extending through the passageway and openings of the inner and outer members, positioning a distal portion of the prosthesis delivery system at the target location within the patient; retracting the outer member in a proximal direction relative to the inner member to simultaneously deploy the prosthesis from the delivery system and laterally separate the guiding member from the inner member. - View Dependent Claims (21, 22)
