Abstract
An arteriovenous graft and methods of reducing the risk of graft thrombosis and extending patency of the arteriovenous graft are provided herein. The arteriovenous graft is operable for attaching to a vein at a venous anastomosis. In some aspects, the arteriovenous graft includes a plurality of grooves at a venous anastomosis end of the arteriovenous graft and the venous anastomoses may be arranged such that the arteriovenous graft and the vein meet at an angle of 30° or less.
