An inventive flanged graft for end-to-side anastomosis includes a tubular graft member and a flanged section The type and size of the flanged section is determined by various factors such as identity of the receiving artery, position of the arteriotomy on the receiving artery, and luminal diameter of the graft. The graft is preferably anastomosed to the receiving artery using continuous sutures to join the arteriotomy to the peripheral edges flanged section.

Flanged graft for end-to-side anastomosis

A medical device which defines a lumen for flowing a bodily fluid from an upstream end of the device to a downstream end thereof is disclosed. The device has a luminal wall () that extends between the upstream and downstream ends and defines the lumen within which the fluid flows. The wall exhibits a succession of protuberances spaced from each other along the length of the device. Each protuberance has a flank facing upstream () and a flank facing downstream (), the flank facing upstream extending into the fluid flow so that a radially outermost part of the flow of fluid from the upstream to the downstream end of the device impinges on the upstream flank and is thereby caused to reverse its flow, and flow upstream from the upstream flank to the downstream flank of the next adjacent protuberance upstream, creating micro-vortices between two adjacent protuberances.

Medical device for fluid flow and method of forming such device

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.

An expanded polytetrafluoroethylene flanged vascular graft (,) suitable for end-to-side anastomosis grafting having an integral terminal polytetrafluoroethylene flanged skirt or cuff section (,) which facilitates an end-to-side anastomosis directly between an artery and the expanded polytetrafluoroethylene flanged bypass graft (,) without need for an intervening venous collar or venous patch.
