Claim Text:
1. A method of creating a venous valve of autologous tissue, the method comprising the steps of: transluminally advancing a delivery system having a valve creation device mounted thereon to a target site within a vein; and deploying the valve creation device within the vein such that the valve creation device in a preset closed configuration forces opposing portions of a wall of the vein together such that the opposing portions of the vein wall substantially close a lumen of the vein and create a valve of autologous vein tissue that substantially prevents retrograde blood flow through the valve, wherein the valve creation device changes shape and assumes a temporary open configuration in response to antegrade blood flow through the vein such that the opposing portions of the vein wall separate to allow blood flow through the created valve.
