Abstract
An endovascular graft for securement within a vessel, duct, or lumen of a living being. The graft comprises a tubular graft sleeve and a plurality of ring-like stents mounted on the outer surface of the sleeve. Anchoring projections are provided on the outer surface of the stents. The graft sleeve has a passageway extending therethrough, which when-the graft is located within the vessel, duct, or lumen serves to carry body fluid, e.g., blood, through it in a single direction. This action produces a force on the tubular sleeve and the plural stents mounted thereon. The anchoring projections extend outward from the outer surface of the stents and are arranged for engagement with the interior of the wall of the vessel, duct, or lumen. The anchoring projections are preferentially oriented to include portions extending at an acute angle to the direction of the fluid flow to tightly engage the interior of the wall of the vessel, duct, or lumen under the force applied by the fluid flowing through the device.
