A vascular graft ( 20 ) comprises a proximal section ( 4 ), integral with two branches ( 2, 3 ) which terminate in a distal end-to-end section ( 30 ). The end-to-end section ( 30 ) is attached to a host artery ( 5 ) at end-to-end anastomoses ( 31, 32 ). Flow of blood from the proximal section ( 4 ) to the host artery ( 5 ) occurs with a self-correcting flow pattern at the opposing junctions, avoiding arterial bed impingement and associated risk of restenosis. |
