Abstract A unitary anastomosis device for use in forming a graft between two body members is provided which includes a body member of fluid impervious vessel compatible material formed to define at least one elongate chamber having at least two spaced open ends. The outer surface of the body member carries a bio-adhesive which bonds the body member to the luminal walls of two vessels to be joined when the body member is expanded into contact with the vessel luminal walls.
