Abstract
A nonmodular endograft system for treating aortic aneurysms involving bilateral renal arteries can include a main fabric cover that is sealed, coupled, or integral, with first and second branch fabric covers. The system can be configured so that after the main cover is expanded in the aorta, and after the two branch covers are respectively expanded in the renal arteries such that (i) the first cover ostium is substantially aligned with the first renal ostium, and (ii) the second cover ostium is not substantially aligned with the second renal ostium, then aortic blood flows from the main cover into each of the branch covers.
Claims11
A method for placing an endograft assembly in an aorta having branching vessels, said method comprising:
- providing an endograft including a main cover, a first branch cover, and a second branch cover;
- implanting the endograft in the aorta between opposed branching vessels or covering adjacent branching vessels, wherein the first branch cover and the second branch cover move relatively freely axially, radially, and rotationally relative to a long axis of the main cover to accommodate different positions of the branching vessels.
