摘要： A system for making a precise incision and circular hole in a vessel wall, such as the aorta, that eliminates lateral side notches from the aortotomy. In one aspect, the system includes a surgical knife or lancet having a blade surrounded by a retractable shield. In one aspect, the system includes a tissue punch having a rotating circumferential edge for receiving a parabolic-shaped anvil having an anvil cutting edge. The anvil is placed through an incision made by a knife and actuated to produce a hole in the vessel wall.
