Abstract
Abstract Anastomosis procedures and anastomosis cutting procedures are achieved with an anvil apparatus that is externally positioned through the wall of a vessel into the vessel lumen. The externally positioned anvil apparatus has an anvil that engages a cutter to form a vessel opening. The anvil is larger than the cutter to enable the vessel to be cut as it is compressed between the cutter and the anvil. The anvil may have a spherical engaging end for use with a cylindrical cutter for forming circular openings in a manner such that the anvil self centers. The anvil and cutter may also be adapted to form elliptical openings. The balloon may be solid or deployable.
