Abstract
The present invention is directed to a cutting apparatus for cutting an opening in a vessel for subsequent anastomosis. The cutting apparatus includes an anvil, an anvil pull and a cutter. The anvil is inserted through a small incision at the anastomosis site and brought into contact with the interior wall of a vessel so that the anvil distends the wall of the vessel. The cutter is then urged against the portion of the vessel wall that is distended by the anvil to form an opening in the vessel wall. The anvil has a surface that is softer than the cutter so that the cutter can cut completely through the vessel and depress into the anvil.
