A support member fixed to the handle body, and a sheath extending about a portion of the support member and fixed to the internal lead screw assembly is provided. Rotating the lead screw nut while abutting the distal grip, causes movement of the internal lead screw assembly relative to the handle. The lead screw nut simultaneously is slidable along the handle body while engaged with the internal lead screw assembly, thereby providing at least two mechanisms for causing movement of the internal lead screw assembly relative to the handle.

DELIVERY SYSTEMS WITH INTRODUCER AND DISTAL SHEATHS AND METHODS OF USE
A delivery system and method of its use delivers a stent graft prosthesis to a surgical site, such as an abdominal, thoracic or thoraco-abdominal aortic aneurysm. The delivery system includes a handle defining a conduit, an introducer sheath extending distally through the handle, a substantially straight inner control tube extending through the conduit of the handle and from the distal end of the introducer sheath, and a distal sheath that extends through and beyond a distal end of the introducer sheath. The distal sheath can have, in one embodiment, a diameter equal to or less than that of the introducer sheath. Retraction of the distal sheath through the introducer sheath and the handle exposes a stent graft prosthesis extending about the inner control tube. Removal of the inner control tube from the introducer sheath allows for implantation of additional components through the introducer sheath.
