Abstract
Supplemental intraluminal graft extension achieved by cuff-means substantially fortify and enhance endovascularly emplaced systems, particularly for bridging aneurysms. Multiple embodiments based upon overlapping of at least two segments are taught. Cuff-means likewise have applications to restore patency to, or substantially enhance, prior failing emplacements of both home-made and other commercial devices.

21. A double-layered intraluminal device, comprising:
-
a first bifurcated prosthesis comprising a first main tubular body portion having a length, a first leg having a first leg length and a second leg having a second leg length which is shorter than the first leg length; and
a second bifurcated prosthesis comprising a second main tubular body portion having a length, a first leg having a first leg length and a second leg having a second leg length which is shorter than the first leg length;
wherein when the intraluminal device is disposed within a vessel of a patient, a majority of the length of the first main tubular body portion overlaps with a majority of the length of the second main tubular body portion, the first leg of the first bifurcated prosthesis extends through the second leg of the second bifurcated prosthesis, and the second leg of the first bifurcated prosthesis extends through the first leg of the second bifurcated prosthesis. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A double-layered intraluminal device, comprising:
-
a first bifurcated prosthesis comprising a first main tubular body portion having a length, a first leg having a first leg length and a second leg having a second leg length which is shorter than the first leg length; and
a second bifurcated prosthesis comprising a second main tubular body portion having a length, a first leg having a first leg length and a second leg having a second leg length which is shorter than the first leg length;
wherein one of the first and second bifurcated prostheses is balloon expandable and the other of the first and second bifurcated prostheses is self expanding and wherein when the intraluminal device is disposed within a vessel of a patient, a majority of the length of the first main tubular body portion overlaps with a majority of the length of the second main tubular body portion, the first leg of the first bifurcated prosthesis extends through the second leg of the second bifurcated prosthesis, and the second leg of the first bifurcated prosthesis extends through the first leg of the second bifurcated prosthesis. - View Dependent Claims (36, 37, 38, 39)

40. A method for positioning a first bifurcated prosthesis and a second bifurcated prosthesis in a vessel of a patient'"'"'s body, the method comprising:
-
introducing a first bifurcated prosthesis comprising a first main tubular body portion having a length, a first leg having a first leg length and a second leg having a second leg length which is shorter than the first leg length;
securing the first bifurcated prosthesis within the body vessel;
introducing a second bifurcated prosthesis comprising a second main tubular body portion having a length, a first leg having a first leg length and a second leg having a second leg length which is shorter than the first leg length;
positioning the second bifurcated prosthesis such that at least a majority of the length of the first main tubular body portion overlaps with a majority of the length of the second main tubular body portion, the first leg of the first bifurcated prosthesis extends through the second leg of the second bifurcated prosthesis, and the second leg of the first bifurcated prosthesis extends through the first leg of the second bifurcated prosthesis.
