An endoluminal graft system comprising an endoluminal graft including a framework and a flexible fabric surrounding the framework, a deflection means configured for placement through an opening to a branching vessel, and a delivery catheter configured to position the endoluminal graft within a primary vessel. A method of implanting the endoluminal graft includes positioning the endoluminal graft within a primary vessel with a leading edge of the endoluminal graft adjacent to an opening to a branching vessel. A deflecting means is positioned through the opening to the branching vessel adjacent to the leading edge of the endoluminal graft. The endoluminal graft is then advanced along the length of the primary vessel with the deflection means engaging the leading edge of the endoluminal graft to form a scallop along the leading edge of the endoluminal graft.
