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.
