Vascular device with valve for approximating vessel wall
First Claim
1. A vascular device comprising:
- a body having a proximal portion and a distal portion and movable from a collapsed insertion position to an expanded position having a larger cross-sectional dimension, the body including a plurality of struts,at least two elongated struts extending distally from the body; and
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, at least a portion of the valve extending distally from the body in the delivery and placement positions, wherein the elongated struts engage a distal portion of the valve in the placement position of the valve to retain the valve.

Abstract
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.

10. A vascular device comprising:
-
a body having a proximal portion and a distal portion; a valve extending distally from the body; and a retraction member connected to the valve; wherein the body and valve are movable between a collapsed insertion position within a delivery sheath to an expanded placement position exposed from the delivery sheath, the body and valve having a larger cross-sectional dimension in the placement position than in the collapsed position, wherein upon exposure from the delivery sheath, the retraction member applies a retraction force to the valve to pull the valve in a proximal direction. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for treating venous valve insufficiency comprising:
-
inserting into a target vessel adjacent the region of the removed portion of valve leaflets a delivery device and a vascular device in an insertion position within the delivery device, the vascular device including a body, a plurality of vessel engaging members extending from the body, a valve, and a retraction member connected to the valve, wherein in the insertion position the body, retraction member and valve are in a reduced transverse dimensional configuration with at least a portion of the valve positioned distal of the body; and exposing the vascular device from the delivery device, wherein the exposure enables the retraction member to move the valve in a proximal direction and the exposure enables the body to expand to enable the vessel engaging members to engage the internal wall of the vessel - View Dependent Claims (20, 21)
