Vascular device and method for valve leaflet apposition
First Claim
Patent Images
1. A method for treating venous valve insufficiency comprising:
- inserting a delivery device and a vascular device into a target vessel adjacent valve leaflets of the vessel;
deploying the vascular device to an enlarged diameter to securely engage the internal wall of the vessel; and
reducing the diameter of the vascular device to move the vessel wall radially inwardly and bring the valve leaflets closer together.

14. A method of approximating vein valve leaflets comprising:
-
inserting a vascular device of shape memory material in a collapsed configuration intravascularly to a target vessel;
actuating an expandable member to expand the vascular device to an expanded configuration to enable wall engaging members of the device to secure the internal vessel wall; and
contracting the expandable member to allow the vascular device to contract towards its memorized expanded configuration to bring the valve leaflets closer together. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
