Claim Text:
1. A stent graft delivery device having two indwelling access sheaths preloaded with a stent graft on the delivery device, the stent graft delivery device comprising; a guide wire catheter having lumen therethrough; a handle assembly at a distal end of the guide wire catheter, the handle including a multiport manifold; a nose cone dilator at the proximal end of the guide wire catheter; a pusher catheter extending from the manifold towards the nose cone dilator, the pusher catheter comprising a longitudinal pusher lumen therethrough that is offset from the center of the pusher catheter and two longitudinal auxiliary lumens, the pusher catheter completely enclosing the two longitudinal auxiliary lumens radially, a sheath disposed coaxially over the pusher catheter and the stent graft, the guide wire catheter extending through the pusher lumen and the guide wire catheter able to move longitudinally and rotationally with respect to the pusher catheter, the pusher catheter comprising a proximal end spaced distally from the nose cone dilator and thereby defining between the proximal end of the pusher catheter and the nose cone dilator a stent graft retention region; the stent graft comprising a stent structure, graft material having a side wall, at least two fenestrations in the side wall of graft material, a proximal end, a distal end and a lumen therethrough; the manifold comprising two elongate side ports and a through bore, the two elongate side ports extending distally at an angle from the through bore, the pusher catheter further comprising two apertures near the distal end of the pusher catheter and the two apertures opening respectively into the two auxiliary lumens, the pusher catheter being in communication with the through bore of the manifold such that the two apertures communicate respectively with the two elongate side ports; an indwelling access sheath within each auxiliary lumen, the indwelling access sheaths each configured to receive a guide wire, the indwelling access sheaths extending through respective elongate side ports, into the manifold from external thereof, into the distal end of the stent graft, through the lumen of the stent graft, and out of respective fenestrations, wherein each of the two apertures of the pusher catheter comprises an elongate groove in the pusher catheter having a proximal end and a distal end and is tapered towards its distal end, and wherein each of the two apertures aligns with its respective elongate side port to provide an uninterrupted lumen from the respective elongate side port and through its respective auxiliary lumen.
