Abstract
A stent graft delivery system includes an internal lead screw assembly within a track of a handle. The internal lead screw assembly is moveable along a major axis of the handle by rotation of a lead screw nut that extends about the handle and is threadably engaged with the threaded portion of the internal lead screw assembly. The lead screw nut is also slidable along the handle while engaged with the internal lead screw assembly. A stent graft system includes a proximal stent adjacent to a bare stent of angled struts joined by proximal and distal apices, wherein the proximal stent is nested within the bare stent.
