  • Soft anvil apparatus for cutting anastomosis fenestra
    Patent number: 6743244
    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.

  • Externally directed anastomosis systems and externally positioned anastomosis fenestra cutting apparatus
    Patent number: 6551334
    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.
