Connecting device for anastomosis, device for fitting fasteners and implant including them

An implant including:

• a tubular prosthesis, comprising a vascular prosthesis, for anastomosis with a tubular conduit in which a lateral or terminal opening is formed, said tubular prosthesis having a connecting end comprising a turned-back portion forming an annular layer whose free edge is adapted to be applied adjacent a rim of the opening in the tubular conduit;
• a connecting device comprising a set of fasteners which form clamps adapted to press said annular layer of said tubular prosthesis onto the rim of the opening of the tubular conduit, and an annular support around which said fasteners are distributed, wherein each of said fasteners includes first and second jaws and is elastically deformable between a rest position in which said first and second jaws are in a closed, clamping position for clamping said annular layer of said tubular prosthesis to the rim of the opening of the tubular conduit, and an open position in which said first and second jaws are spread apart to enable said fastener to be fitted to said annular layer of said tubular prosthesis and the rim of the opening of the tubular conduit in preparation for clamping thereof;
• and
• a releasable retaining mechanism for releasably holding said fasteners of said connecting device in said open position.
