Abstract
A positionable stent-graft delivery system includes a stent-graft, a tip capture mechanism radially constraining a proximal portion of an anchor stent ring of the stent-graft, and a positioning mechanism for positioning the tip capture mechanism. The positioning mechanism includes tensioner guides and cords. To position the tip capture mechanism, a cord is retracted through the respective tensioner guide, e.g., by the physician. Retraction of the cord, in turn, pulls the tip capture mechanism towards a distal end of the tensioner guide. In this manner, the stent-graft is readily repositioned.
