This is an implantable device intended generally for forming an anastomosis between a lumen of the body and an intersecting graft lumen. The device may be configured to form an anastomosis which is entirely lined with live tissue, or it may be configured to form an anastomosis with synthetic material defining at least a portion of one of the intersecting lumens.

[ What is claimed is:] [1.]1. An anastomosis device for joining the end of a tubular graft having a graft lumen with a tissue wall having an interior side and an exterior side comprising:a. an implantable structural member having proximal and distal structural member ends, a longitudinal axis, an outer structural member surface, a structural member inner lumen, and at least two radial extensions extending outward from said structural member surface at the distal structural member end; andb. an implantable fastener having proximal and distal fastener ends and an inner fastener surface configured to slidably interface with said outer structural member surface,wherein said proximal end of said implantable structural member is configured to attach to said end of said tubular graft and fluidly connect said structural member lumen with said graft lumen,wherein said at least two radial extensions are configured to bend toward the outer structural member surface when said implantable structural member is urged, distal structural member end first, through an aperture in said tissue wall and to bend away from said outer structural member surface to prevent said implantable structural member from being removed from said aperture when said implantable structural member is urged in a reverse direction, andwherein said implantable fastener is operable to be moved distally along said outer structural member surface to reach a sustainable position wherein said tissue wall and said end of said tubular graft are retained in compression against each other between said implantable fastener and said at least two radial extensions.
