Claim Text:
1. A stent graft delivery system, comprising: a) a handle that includes b) an outer sheath defining a lumen and extending through the conduit and moveable relative to the handle; c) an internal lead screw assembly within the track, the internal lead screw assembly linked to the outer sheath and being moveable along a major axis of the conduit, and including a threaded portion that extends through the track; d) a lead screw nut that extends externally around the handle body and is threadably engaged with the threaded portion of the internal lead screw assembly, whereby rotation of the lead screw nut while abutting the distal grip causes retraction of the internal lead screw assembly and the outer sheath relative to the handle, and wherein the lead screw nut simultaneously is slidable along the handle body while engaged with the internal lead screw assembly and the outer sheath without requiring rotation of the lead screw nut, thereby providing at least two mechanisms for causing retraction of the internal lead screw assembly and the outer sheath relative to the handle.
