摘要: A medical punch includes a longitudinally dividable anvil with a reduced cross-sectional dimension facilitating insertion of the anvil into the vessel wall to achieve a clean aperture in the vessel wall by cooperative shearing action of a cutting edge and an anvil edge. In another embodiment, the instrument incorporates a measuring device for determining the thickness of a vessel wall between an anvil and a distal end of a cylindrical structure which together form a caliper, and the measuring device can also constitute a medical punch by cooperative shearing action of a cutting edge and an anvil to achieve a clean aperture in the vessel wall.

摘要: Forming a proximal anastomosis on an aortic wall includes method and instrumentation and apparatus for forming an aortic puncture and inserting into the vessel through the puncture a fluid-impervious sealing element with a protruding retainer. An anastomosis of a graft vessel over the puncture is partially completed with the retainer of the sealing element protruding through the partial anastomosis. The retainer facilitates removal of the sealing element from the partial anastomosis prior to completion of the procedure.
