Connecting device for anastomosis, device for fitting fasteners and implant including them
First Claim
1. A connecting device for anastomosis of a tubular prosthesis to a tubular conduit in which a lateral or terminal opening is formed, the 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, said connecting device comprising:
- a set of fasteners which form clamps adapted to press the annular layer of the 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 the annular layer of the 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 the annular layer of the prosthesis and the rim of the opening of the tubular conduit in preparation for clamping thereof.

Abstract
The invention concerns a connecting device for anastomosis of a vascular prosthesis to a tubular conduit in which a lateral or terminal opening has been formed, the prosthesis including, at a connecting end, a turned-back portion forming an annular layer whose free edge is adapted to be pressed onto the immediate vicinity of the rim of the tubular conduit. The connecting device includes a set of fasteners each of which is adapted to press the annular layer onto the rim of the opening. It further includes an annular support along which the fasteners are distributed. The fitting device includes a connecting device and a releasable holding mechanism for holding the fasteners in the open position. The implant comprises a vascular prosthesis and a fitting device.

6. An apparatus for anastomosis of a tubular prosthesis to a tubular conduit in which a lateral or terminal opening is formed, the 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, said apparatus comprising:
-
a connecting device comprising a set of fasteners which form clamps adapted to press the annular layer of the 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 the annular layer of the 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 the annular layer of the 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. - View Dependent Claims (7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
