Abstract
A surgical staple having at least one projection formed thereon. In various embodiments, the projection is formed on a crown of the surgical staple. In one various embodiment, the projection surrounds, or is positioned adjacent to, at least one deformable member of the surgical staple. In one embodiment, the projection can apply an increased compressive force or pressure to soft tissue surrounding the deformable member prior to the deformable members puncturing a hole in the soft tissue. As a result of the increased compressive force or pressure on the tissue, after staple deployment, blood flow proximate deformable member puncture holes can be reduced.
