Debranching Visceral Stent Grant and Methods for Use
A visceral double-barreled main body stent graft and methods for its use, the stent graft comprises, a main body stent graft having distal and proximal ends, the main body stent graft's length ranges from about 100-120 mm and diameter at the proximal end ranges from about 30-45 mm, first and second lumens defined at the main body stent graft's distal end, the first lumen's diameter ranges from about 18-20 mm, the second lumen's diameter ranges from about 16-18 mm, the first and second lumens have about the same length from about 50-70 mm, the first lumen is secured to the second lumen along a shared length, and the main body stent graft defines a tubular wall that is contiguous with the first and second lumens such that any fluid entering the main body must exit through one of the first or second lumens.
1 . A debranching stent graft comprising:
a first bifurcated stent graft having a first bifurcation defining a first leg and a second leg each extending away from the first bifurcation, wherein the first bifurcated stent graft has a distal end and a proximal end, and wherein a diameter of the proximal end of the first bifurcated stent graft is greater than each of a diameter of the first leg and a diameter of the second leg, and wherein a length of the first leg of the first bifurcated stent graft is equal to a length of the second leg of the first bifurcated stent graft;
an extension stent graft having a distal end and a proximal end, wherein the distal end of the extension stent graft is coupled to the proximal end of the first bifurcated stent graft;
a second bifurcated stent graft having a second bifurcation defining a first leg and a second leg, wherein the second bifurcated stent graft has a distal end and a proximal end, wherein the first leg of the second bifurcated stent graft is coupled to the proximal end of the extension stent graft; and
a main body stent graft having a distal end and a proximal end, wherein the distal end of the main body stent graft is coupled to the proximal end of the second bifurcated stent graft.
