  • Method and apparatus for achieving hemostasis along a staple line
    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.
