Abstract
Compression plate apparatus enables vessels to be joined together in various anastomosis configurations. The compression plates are guided to each other in a parallel orientation by guides. The compression plate apparatus may be utilized with an intraluminally directed anvil apparatus or an externally positioned anvil apparatus. One of the compression plates assists in the eversion of the anastomosis fenestra contour. One of the compression plates enables a graft vessel to be pre-everted so that the anastomosis fenestra contours are everted. The apparatus provides a structure that enables the vessels to be joined without being penetrated.
Claims16
A compression plate anastomosis system for anastomosing vessels, comprising:
- an anvil apparatus including anvil means for engaging the interior surface of a first vessel at an anastomosis site, and anvil pull means for holding the engaging end of the anvil means against the interior of the first vessel, the anvil pull means extending from the engaging end of the anvil means,
- a compression plate apparatus including
- a first compression plate having a first compression plate opening;
- wherein the first compression plate opening is defined by first holding means for holding a portion of a first vessel that defines a first vessel opening,
- wherein said first holding means extends from said first compression plate;
- and
- a second compression plate having a second compression plate opening;
- wherein the second compression plate opening is defined by second holding means for holding a portion of a second vessel that defines a second vessel opening;
- wherein the openings of the first and second compression plates are sized and oriented to permit the anvil apparatus to be pulled through both openings;
- wherein the anvil apparatus and the compression plate apparatus are adapted to enable a cutting means for forming the first vessel opening in the first vessel to pass through the second compression plate opening and form the first vessel opening by engaging the engaging end of the anvil means and to then enable the anvil apparatus to be pulled through the first vessel opening and the first compression plate opening in a manner such that the portion of the first vessel defining the first vessel opening is at least partially everted and is not penetrated by the action of the anvil means passing through the first vessel opening and the first compression plate opening.
