Claim:
1. A deployment system for deploying a self-expanding fenestrated stent graft comprising: an introducer having a proximal end intended to be employed in a patient during use and a distal end intended to remain outside of the patient during use, a nose cone at the proximal end of the introducer; a stent graft retained on the introducer and having a main graft body, a proximal end, a distal end, a lumen from the proximal end of the stent graft to the distal end of the stent graft, a graft wall and a fenestration in the graft wall configured to receive a side arm, and at least one self-expanding stent supporting the main graft body; a main catheter disposed in the introducer and extending from the distal end of the introducer to the proximal end of the introducer, the main catheter having a lumen configured to slidably receive a guide wire in the lumen of the main catheter; an auxiliary catheter preloaded within the introducer prior to delivery to a patient at least partially adjacent the main catheter, the auxiliary catheter including an auxiliary lumen configured to receive an auxiliary guide wire slideably disposed in the auxiliary lumen, the auxiliary catheter extending from a distal position to the distal end of the stent graft, into the lumen of the stent graft and through the fenestration, wherein the auxiliary catheter is preloaded at least partially within the lumen of the stent graft, through the fenestration, and through a longitudinal notch of the nose cone.
