Abstract:
1. A laparoscopic deployment device in combination with a laparoscopic conduit, the laparoscopic conduit comprising, an elongate graft tube comprising a proximal end and a distal end, the proximal end comprising at least two self expanding stents affixed thereto to keep the proximal end of the elongate graft tube open in use, there being a gap between the at least two stents to provide a sealing region to seal through an aperture in a vessel wall, the at least two self expanding stents including a distal most stent that is further from the proximal end of the elongate graft tube than the other of the at least two self expanding stents, and the elongate graft tube comprising an elongate distal unstented portion, the deployment device comprising, a pusher catheter comprising a proximal end, a guide wire catheter extending from the pusher catheter to a nose cone dilator, the nose cone dilator comprising a distal end, and a pusher catheter extension being of lesser diameter than the pusher catheter, the pusher catheter extension extending from the proximal end of the pusher catheter, a sheath extending from a sheath manipulator on the pusher catheter to the nose cone dilator thereby defining an annular space between the pusher catheter extension and the sheath, the laparoscopic conduit being mounted onto the delivery device whereby the pusher catheter extension extends proximally through the elongate distal unstented portion of the elongate graft tube in the annular space between the pusher catheter extension and the sheath, the pusher catheter extension bearing against the distal most stent and the proximal end of the laparoscopic conduit extending to the distal end of the nose cone dilator, the laparoscopic conduit being retained in a contracted condition by the sheath between the distal end of the nose cone dilator and the proximal end of the pusher catheter, whereby the pusher catheter extension bearing against the distal most stent on the laparoscopic conduit prevents distal movement of the laparoscopic conduit during retraction of the sheath during deployment of the laparoscopic conduit.
