1. A vascular device comprising:
a body formed from a tubular member and having a proximal portion and a distal portion and movable from a collapsed delivery position to an expanded placement position having a larger cross-sectional dimension, the body including a plurality of first struts forming a plurality of cells; at least two elongated struts formed from the tubular member and integral with the first struts, the at least two elongated struts extending distally from the plurality of cells, and each elongated strut having a portion extending radially inwardly to extend transverse to a longitudinal axis of the device in an unconstrained position; a plurality of vessel engaging members extending outwardly from the body for engaging the internal wall of a vessel; and a valve movable between a collapsed delivery position and an expanded placement position, in the collapsed delivery position the valve spaced distally of the plurality of cells, at least a portion of the valve extending distally from a distal portion of the body in the placement position, wherein the elongated struts are positioned external of the valve and engage and lie over a distalmost edge of the valve in the placement position of the valve to retain the valve, the vessel engaging members positioned proximal of the valve, the valve engaged by the radially inwardly extending portions of the at least two elongated struts. |
