  • Patent number: 5641111
    Abstract: An anvil for a surgical fastener assembly is disclosed. The anvil has a staple-forming surface upon which a plurality of pockets are displayed for staple formation. First and second sidewalls extend from the staple-forming surface. Cutting guides extend laterally from the sidewalls to provide a uniform surface upon which a user can apply pressure with a scalpel to staple tissue in a direction generally parallel to the vertical staple row. An even margin can be maintained between the staple row and the cut line, thus increasing the degree of confidence and skill that the user can employ when cutting the fastened tissue.

  • Patent number: 5263629
    Abstract: A method and apparatus to achieve hemostasis along a staple line by utilizing a pledget material positioned adjacent at least one surface of tissue. A line of staples extends through the tissue and the pledget material. The pledget material substantially uniformly distributes pressure along the staple line and thereby causes substantial hemostasis along the tissue cut. The pledget material may also absorb blood that may escape from a partially open blood vessel.
