1. A method for deploying a graft having a bifurcation for repairing an aortic aneurysm proximate to an aortic bifurcation associated with first and second iliac arteries of a patient, the method comprising the steps of:

  • providing a graft having a main tubular body, a first tubular leg and second tubular leg the main tubular body having a main opening associated therewith, the first tubular leg having a first opening associated therewith and the second tubular leg having a second opening associated therewith the second tubular leg further includes a lead tube attached to the second tubular leg proximate the second opening;

    folding the second tubular leg of the graft so the second opening and the main opening are oriented in the same general direction and so that the second tubular leg lies substantially parallel to the main tubular body of the graft to provide a folded-over second leg;

    introducing the lead tube attached to the folded-over second leg through a first iliac artery of a patient and continuing to advance the graft until the main tubular body of the graft is disposed proximate an aortic aneurysm proximate to an aortic bifurcation, the aortic aneurysm having a proximal end;

    securing the main tubular body proximal to the proximal end of the aortic aneurysm;

    moving the folded-over second leg of the graft into a second iliac artery by pulling on the lead tube;

    securing the first tubular leg of the graft in the first iliac artery; and

    securing the second tubular leg of the graft in the second iliac artery.
