Abstract

A staple cartridge comprising a cartridge body, a surgical staple, and a compressible member is disclosed. The surgical staple is movable from an unfired position to a fired position. The surgical staple is deformable from a first shape in the unfired position to a second shape in the fired position during a firing stroke. The surgical staple is ejected from the cartridge body during the firing stroke. The surgical staple comprises a crown, a first deformable member extending from the crown, and a second deformable member extending from the crown. The compressible member is positioned intermediate the first deformable member, the second deformable member, and the crown after the surgical staple has been deformed into the second shape. The compressible member is at least partially positioned between the first deformable member and the second deformable member of the surgical staple when the surgical staple is in the unfired position.
