HEMOSTASIS VALVE AND DELIVERY SYSTEMS

Abstract: a method of delivering a stent graft includes providing a handle that comprises an internal lead screw assembly within the track, the internal lead screw assembly, a lead screw nut that extends about the handle body, whereby a user's rotation of 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. 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.
