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;
a first bifurcation in the main body stent graft defining a first lumen and a second lumen;
a second bifurcation within the first lumen defining a first leg and a second leg;
a third bifurcation within the first leg defining a third leg and a fourth leg; and
a fourth bifurcation within the second leg distal to the second bifurcation defining a fifth leg and a sixth leg, wherein the main body stent graft, 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.
