A prosthesis (1) has a graft sleeve having a first and second ends (9A, 9B) with a lumen therethrough, a main body portion (2) bifurcated at a junction (6) to form a first leg (3) and a second leg (4) such that the lumen of the graft sleeve in main body portion (2) is divided into two smaller lumens. The body portion (2) has two ring stents (7), first leg (3) and second leg (4) each have ring stents (7) which maintain the patency of legs (3, 4) and assist bending of the leg graft without kinking to accommodate the patient's anatomy. The first leg (3) and second leg (4) each include a fenestration (5) in the fabric material forming each leg. Corrugations in first leg (3) and/or second leg (4) allow a degree of twisting to accommodate angular adjustment of the fenestration position. |
