ENDOLUMINAL PROSTHESIS INTRODUCER
First Claim
1. An endoluminal prosthesis introducer comprising:
- a rotatable inner cannula comprising a proximal end;
a proximal tip disposed at the proximal end of the inner cannula and comprising a distal end; and
a retaining member comprising an engaging member extending radially outward, the retaining member disposed about the proximal end of the inner cannula, whereby, in response to rotation of the inner cannula with respect to the retaining member, the proximal tip is longitudinally movable relative to the engaging member between a retaining configuration and a releasing configuration, wherein the proximal tip and the engaging member are spaced from one another by a greater longitudinal distance in the releasing configuration than in the retaining configuration.

Abstract
An endoluminal prosthesis introducer may include a rotatable inner cannula including a proximal end. The introducer may include a proximal tip disposed at the proximal end of the inner cannula and including a distal end. The introducer may include a retaining member including an engaging member extending radially outward. The retaining member may be disposed about the proximal end of the inner cannula. In response to rotation of the inner cannula with respect to the retaining member, the proximal tip may be longitudinally movable relative to the engaging member between a retaining configuration and a releasing configuration. The proximal tip and the engaging member may be spaced from one another by a greater longitudinal distance in the releasing configuration than in the retaining configuration.

13. A system comprising:
-
an introducer and an endoluminal prosthesis loaded on the introducer; the prosthesis comprising a stent end engaged by the introducer and retained in a compressed configuration; the introducer comprising; a rotatable inner cannula comprising a proximal end; a proximal tip disposed at the proximal end of the inner cannula and comprising a distal end; and a retaining member disposed about the proximal end of the inner cannula and comprising a sleeve and an engaging member extending radially from the sleeve and engaged with the stent end in the compressed configuration, whereby the stent end is retained against the distal end of the proximal tip, and, in response to rotation of the inner cannula with respect to the prosthesis and the retaining member, the proximal tip is longitudinally movable relative to the engaging member from a retaining configuration to a releasing configuration, and the stent end is releasable from engagement with the engaging member. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method for deploying an endoluminal prosthesis within a body vessel, the method comprising:
-
introducing the prosthesis into the body vessel with an introducer, the introducer comprising an inner cannula, a proximal tip disposed at a proximal end of the inner cannula, and a retaining member disposed about the proximal end of the inner cannula and engaged with a stent end of the prosthesis, the stent end captured between the retaining member and a distal end of the proximal tip and retained in a compressed configuration; and moving the proximal tip proximally relative to the retaining member by rotating the inner cannula relative to the retaining member.
