| 发明名称 | Methods for fluid flow through body passages | ||
| 摘要 | A device includes a first end portion, a second end portion, an intermediate portion between the first end portion and the second end portion, and a graft material coupled to at least the intermediate portion. The first end portion has a first end diameter. The second end portion has a second end diameter larger than the first end diameter. The intermediate portion tapers between the first end portion and the second end portion. A method of diverting fluid flow from a first passage to a second passage comprising deploying the device in a third passage between the first passage and the second passage, expanding the first end portion against sidewalls of the first passage, and expanding the second end portion against sidewalls of the second passage. | ||

| 主权项 | 1. A method of diverting fluid flow from a first passage to a second passage, the method comprising: deploying a device in the first passage, the second passage, and a third passage between the first passage and the second passage, the device comprising: a first end portion having a first end diameter sized to correspond to a diameter of the first passage; anda second end portion having a second end diameter larger than the first end diameter, the second end diameter sized to correspond to a diameter of the first passage; and wherein deploying the device in the first passage, the second passage, and the third passage comprises: expanding the first end portion coaxial with and against sidewalls of the first passage; andexpanding the second end portion coaxial with and against sidewalls of the second passage. | ||
