Abstract

A bifurcated stent graft includes a stent graft body that defines exactly one main body opening and at least two exit openings. The stent graft body includes at least one stent attached to a graft fabric material, and includes a dividing wall that divides a combined flow path, into a first flow path and a second flow path that each terminate at one of the respective exit openings. The dividing wall includes a thickness profile that terminates at a leading edge radius that extends across a width of the combined flow path.
