Combination double-barreled and debranching stent grafts and methods for use
First Claim
1. A stent graft comprising:
- a main body stent graft defining a single lumen and having a distal end and a proximal end;
a first bifurcation in the main body stent graft defining a first lumen and a second lumen, wherein the main body stent graft defines a tubular wall that is contiguous with the first lumen and the second lumen such that any fluid entering the main body stent graft enters unimpeded and must exit by entering one of the first lumen or the second lumen, wherein the main body stent graft has a diameter at the proximal end in the range from about 28 mm to about 42 mm, wherein the first lumen has a diameter in the range from about 22 mm to about 28 mm and the second lumen has a diameter in the range from about 16 mm to about 22 mm;
a second bifurcation within the first lumen defining a first leg and a second leg, wherein the first leg and the second leg each have a diameter in the range from about 14 mm to about 16 mm;
a third bifurcation within the first leg about 0 mm to about 10 mm distal from the second bifurcation defining a third leg and a fourth leg, wherein the third leg and the fourth leg each have a diameter in the range from about 7 mm to about 12 mm, wherein the third leg and the fourth leg each have a length in the range from about 30 mm to about 50 mm; and
a fourth bifurcation within the second leg between about 10 mm and about 20 mm distal from the second bifurcation defining a fifth leg and a sixth leg, wherein the fifth leg and the sixth leg each have a diameter in the range from about 7 mm to about 12 mm, wherein the third leg and the fourth leg each have a length in the range from about 30 mm to about 50 mm,wherein the main body, the first lumen, the second lumen, the first leg, the second leg, the third leg, the fourth leg, the fifth leg and the sixth leg comprise a single unitary structure having a common graft covering configured such that blood flow is compartmentalized upon deployment.

Abstract
A combination double-barreled and debranching stent graft and methods for its use, where the stent graft comprises, a main body stent graft defining a single lumen with distal and proximal ends, a first bifurcation in the main body defining first and second lumens, 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 stent graft must exit by entering one of the first or second lumens, (c) a second bifurcation within the first lumen defining a first leg and a second leg, (d) a third bifurcation within the first leg defining a third leg and a fourth leg, and (e) a fourth bifurcation within the second leg between about 10 mm and about 20 mm distal from the second bifurcation defining a fifth leg and a sixth leg.
