1. A two piece prosthetic graft for intraluminally bypassing an aneurysm, defect or injury in a vessel wall close to or involving a bifurcation of a trunk vessel having a trunk vessel wall and lumen into first and second branch vessels having first and second branch vessel walls and lumens, said graft comprising:

  • a first graft prosthesis having a continuous side wall extending a length between a first leg opening stent adapted to be expanded into contact with the first branch vessel wall and to define a first leg opening and a second leg opening stent adapted to be expanded into contact with the second branch vessel wall and to define a second leg opening, means for defining a waist opening formed in said fabric side wall along the length of said first graft prosthesis, the continuous side wall and first and second leg opening stents being expandable to an expanded state bridging the bifurcation with said waist opening adapted to be oriented to face away from the bifurcation and toward the lumen of the trunk vessel to provide an attachment seat of predetermined size and defining a first graft lumen extending between said expanded waist lumen and said expanded first leg opening in the first branch vessel lumen and said second leg opening in the second branch vessel lumen; and

    a second graft prosthesis formed of tubular member having a length and a continuous side wall between distal and proximal ends and defining a second graft lumen extending between distal and proximal leg openings, respectively, the tubular member having a collapsed state for advancement of said proximal end into alignment with respect to said waist opening and bridging said aneurysm, defect or injury and being expandable in size to an expanded state with said proximal end thereof expanded into engagement with said attachment seat and the distal end thereof bearing against and restrained by the trunk vessel wall beyond the area of the aneurysm to seal the first and second graft lumens with the trunk vessel lumen and from the aneurysm.
