Patent ID: 8109949

Claim:
A compression plate anastomosis system, comprising: an anvil apparatus comprising an anvil comprising a landing between an engaging end and a terminal end, and an anvil pull extending from the engaging end of the anvil and configured to control the movement of the anvil; a compression plate apparatus comprising a first compression plate comprising a first ring and a first plurality of holding tabs extending from the first ring, wherein said first plurality of holding tabs defines a first compression plate opening; and a second compression plate having a second compression plate opening; wherein the engaging end and the landing of the anvil are sized for movement within the first compression plate opening in a manner that permits a part of a wall of a first vessel at an anastomosis site to be held between the landing of the anvil and the first plurality of holding tabs of the first compression plate without penetration of the held part; wherein the landing and the first plurality of holding tabs are sized relative to each other such that the landing is sufficiently longer than the length of the first plurality of holding tabs to permit at least a portion of a region of the wall of the first vessel extending beyond the part held between the landing of the anvil and the first plurality of holding tabs to rest on the landing of the anvil after formation of an anastomosis opening in the first vessel; wherein the landing of the anvil and the first plurality of holding tabs are sized to permit the part of the wall of the first vessel held between the landing of the anvil and the first plurality of holding tabs of the first compression plate to be held with sufficient force to prevent movement of the held part as the first vessel portion is moved on the landing by the second compression plate such that the first vessel portion becomes at least partially everted over the first plurality of holding tabs of the first compression plate.
