A stent-graft is provided that includes a bifurcated stent (12) adapted for placement at the bifurcation of a bifurcated body lumen. The stent-graft further includes a graft (20) that lines or covers at least part of the bifurcated stent. The graft defines a fluid passageway from the unbifurcated portion into one of the bifurcated stent branches. A closure prevents fluid from flowing through the second of the branches and into the other branch of the body lumen.
