Abstract
An inventive flanged graft for end-to-side anastomosis includes a graft with bifurcated flanges. The bifurcated flanges may be symmetrical or asymmetrical relative to one another. The type and size of flange to be used is determined by various factors such as identity of the receiving artery, position of the arteriotomy on the receiving artery, and lumenal diameter of the graft. The graft is preferably anastomosed to the receiving artery using continuous sutures to join the arteriotomy to the peripheral edges of the bifucated flanges. In an alternate embodiment, the inventive bypass graft includes a flared skirt which extends circumferentially about the tubular graft member. The flared skirt has an elliptical shape and is offset from a central longitudinal axis of the graft member.
