| 摘要 |
The present invention describes improvements for prosthetic devices used for end-to-side, end-to-end and side-to-side anastomosis, without clamping and sutureless or with quick clamping and sutureless, where the tubular member of the prosthesis, besides having its intraluminal part (2) angled in relation to the flange (1), can also have more than one intraluminal part (2), in form of Y, T, among other variations. The flange (1) can also be with or without openings or small handles (4) and chamfers (8), allowing the tie-up to the external part of the tissue, vein, artery or tubular organ to eliminate the contact of foreign bodies inside the anastomosis. The prosthesis can also be without flange (1) or have a tubular member (2) with tapered center to peripheral part or from external part to intraluminal one, and it can be cut in the desired size and gauge. Therefore, the prosthesis can have varied sizes and shapes to accommodate varied graft sizes and types in a simultaneous way.
