摘要： A vascular graft comprising a proximal section, iliac distal legs and a bifurcation blending section (7) between the proximal section and the distal legs. The cross-sectional area of the proximal section at the bifurcation point is less than or equal to the sum of the two cross sectional areas of both iliac legs. The blending section (7) generates a smooth transition from the proximal section to both iliac legs which minimizes wave reflections by ensuring that the area ratio at the bifurcated junction (7) is as close to unity or greater than unity as possible. The blending section (7) defines a first lumen for fluid flow from the proximal section into the first distal leg, and a separate second lumen for fluid flow from the proximal section into the second distal leg. The two lumen are separated by means of a gradual flow which separates the fluid flow from the proximal section into each lumen. The distal legs are connected to the blending section (7) at the bifurcation region to form a substantially “Y”-shaped graft.
