Devices for fluid flow through body vessels
First Claim
1. A device for supplying fluid flow in a human or animal body, the device comprising:
- a first end portion configured to anchor the device in a first vessel;
a second end portion configured to anchor the device in a second vessel different than the first vessel, wherein the first end portion and the second end portion are diametrically expandable to anchor the device in the first vessel and the second vessel;
an intermediate portion located between the first end portion and the second end portion, the intermediate portion configured to permit movement of the first end portion and the second end portion relative to each another, the intermediate portion being diametrically expandable to dilate at least the intermediate portion;
a fluid pathway at least partially defined by the first end portion, the second end portion, and the intermediate portion;
a support structure comprising a mesh extending between the first end portion and the second end portion; and
a polymer tube at least partially defining a lumen, the lumen comprising at least a portion of the fluid flow pathway,wherein the first end portion, the second end portion, and the intermediate portion are self-expanding, andwherein the intermediate portion is configured to be expanded by a balloon after self-expanding.

Abstract
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.
