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.

20. A staple cartridge for use with a surgical stapler, comprising:
-
a staple movable between an unfired configuration and a fired configuration to fasten tissue, said staple comprising; a base; and a deformable member extending from said base; a staple cartridge body, wherein at least a portion of said deformable member is removably stored within said staple cartridge body; and a pressure distribution member, wherein said deformable member is slidable relative to said pressure distribution member, said pressure distribution member comprising; a base facing side; and a tissue facing side, wherein said tissue facing side and said deformable member define a tissue entrapment area therebetween when said staple is in said fired configuration, wherein said pressure distribution member and said staple are positioned on the same side of the tissue prior to moving said staple to fasten the tissue, and wherein said deformable member is partially positioned within said pressure distribution member in said unfired configuration.
