A vascular device comprising a body movable from a collapsed insertion position to an expanded position having a larger cross-sectional dimension. The body includes a plurality of struts. At least two elongated struts extend distally from the body. A plurality of vessel engaging members extend outwardly from the body for engaging the internal wall of a vessel. A valve is movable between a collapsed delivery position and an expanded placement position, wherein at least a portion of the valve extends distally from the body in the delivery and placement positions and the elongated struts engage a distal portion of the valve in the placement position of the valve to retain the valve.
