The invention relates to an anastomotic device for joining one end of a graft vessel to a target vessel at an opening made in the wall thereof The anastomotic device comprises a tubular body on which an outer flange, which comes into contact with the outside of the wall of the target vessel around the opening, and an inner flange, which comes into contact with the inside of the wall of the target vessel around the opening, are arranged. The inner flange is made up of a number of arms which are able to move from an extended position, located in the extension of the tubular body, under the influence of a pretension into a position extending in the lateral direction with respect to the tubular body, after the pretension has been released, in order to form the inner flange. The invention further relates to an anastomotic device comprising a tubular body with an outer flange and an inner flange thereon, the outer flange and optionally also the inner flange being cylindrically curved with a radius of curvature approximately equal to the radius of curvature of the target vessel. |
