摘要：
A device includes a first end portion, a second end portion, an intermediate portion, and a graft material. The first end portion has a first end diameter. The second end portion has a second end diameter smaller than the first end diameter. The first end portion comprises a first material. The second end portion comprises a second material different than the first material. The intermediate portion is between the first end portion and the second end portion. The intermediate portion tapers between the first end portion and the second end portion. The graft material is coupled to at least the intermediate portion.
