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.
Claims19
A bifurcated stent graft comprising:
- a stent graft body defining 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, a bifurcation and 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;
- and
- the dividing wall includes a thickness profile that terminates at a leading edge radius that extends across a width of the combined flow path.
A bifurcated stent graft comprising:
- a stent graft body defining 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, a bifurcation and 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;
- and
- wherein the dividing wall has a height that extends from a bifurcation to the leading edge radius in a direction of the main body opening.
A bifurcated stent graft comprising:
- a stent graft body defining 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, a bifurcation and 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;
- and
- the dividing wall includes a thickness profile that terminates at a leading edge radius that extends across a width of the combined flow path;
- wherein flow entering the stent graft at the main body opening is split and destined for one of the two exit openings at the leading edge radius rather than at a bifurcation of the bifurcated stent graft.
