An intraluminal prosthesis for strengthening a lumen, the prosthesis comprising: a tubular graft comprising a hollow flexible body having a proximal end, a distal end, an exterior surface and an interior surface; at least one self-expanding zigzag stent coupled to the exterior surface of the body; and a balloon expandable tubular stent discrete from the at least one self-expanding zigzag stent, the balloon expandable tubular stent having a first diameter and a second expanded diameter and coupled to the interior surface of the body between the proximal end and the at least one self-expanding zigzag stent; wherein the or each self-expanding zigzag stent provides just enough radial force to expand the intraluminal prosthesis to the vicinity of the interior surface of the lumen; wherein the balloon expandable tubular stent comprises a wire formed into a serpentine configuration including a series of straight sections and a plurality of bends, said straight sections being joined by said bends to form a series of alternating loops, said serpentine configuration being formed into a cylindrical shape having a longitudinal axis and wherein said straight sections are bent into generally circular configurations surrounding and generally perpendicular to said axis; wherein the balloon expandable tubular stent is expandable to the second diameter by application of an outwardly extending force from the interior of the tubular stent, and the second diameter is at least equal to the interior diameter of the hollow flexible body such that the balloon expandable tubular stent provides force for sealing the intraluminal prosthesis to the interior surface of the lumen. a tubular graft comprising a hollow flexible body having a proximal end, a distal end, an exterior surface and an interior surface; at least one self-expanding zigzag stent coupled to the exterior surface of the body; and a balloon expandable tubular stent discrete from the at least one self-expanding zigzag stent, the balloon expandable tubular stent having a first diameter and a second expanded diameter and coupled to the interior surface of the body between the proximal end and the at least one self-expanding zigzag stent; wherein the or each self-expanding zigzag stent provides just enough radial force to expand the intraluminal prosthesis to the vicinity of the interior surface of the lumen; wherein the balloon expandable tubular stent comprises a wire formed into a serpentine configuration including a series of straight sections and a plurality of bends, said straight sections being joined by said bends to form a series of alternating loops, said serpentine configuration being formed into a cylindrical shape having a longitudinal axis and wherein said straight sections are bent into generally circular configurations surrounding and generally perpendicular to said axis; wherein the balloon expandable tubular stent is expandable to the second diameter by application of an outwardly extending force from the interior of the tubular stent, and the second diameter is at least equal to the interior diameter of the hollow flexible body such that the balloon expandable tubular stent provides force for sealing the intraluminal prosthesis to the interior surface of the lumen.
