Abstract:
A pre-loaded stent graft delivery device and stent graft, the stent graft delivery device. The stent graft has at least one fenestration or side arm and the fenestration is preloaded with an indwelling guide wire. The indwelling guide wire are configured to receive the access sheaths. A handle assembly at a distal end of the guide wire catheter. The handle includes a multiport manifold with access ports to the auxiliary lumens in the pusher catheter. Upon deployment of the stent graft into the vasculature of a patient, the indwelling guide wire can be used to facilitate cathertization of a side branch or target vessel through the fenestration or be used to stabilize the access sheath during catheterization, advancement of the access sheath into the target vessel and deployment of a covered or uncovered stent therein through the access sheath.

Claim (Index 13):
A stent graft delivery device comprising;\n a guide wire catheter having a guide wire 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 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 configured 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 to define a stent graft retention region between the proximal end of the pusher catheter and the nose cone dilator; the proximal end of the pusher catheter forming a scalloped end with two proximal openings each defining a proximal opening for one of the two longitudinal auxiliary lumens; the stent graft comprising a stent structure, graft material having a side wall, at least two fenestrations in the side wall of the graft material with a high flexibility side arm extending from each fenestration, a proximal end releasably retained within the distally facing capsule, a scallop in the proximal end of the graft, 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 guide wire within each auxiliary lumen, the indwelling guide wires each configured to slidably receive an access sheath, the indwelling guide wires 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.
