Abstract
Surgical staples including features which can cooperate with staple cavities in a staple cartridge in order to reduce, or even prevent, the surgical staples from rocking, rotating or tilting, within the staple cavities while the staples are deployed by a staple driver, especially when the staples are oriented at different directions. In various embodiments, the surgical staples can include crowns having arcuate and/or cylindrical features which can cooperate with arcuate and/or cylindrical features of the staple cavities in order to reduce unwanted relative movement, or rotation, between the staples and the staple cavities.
