Abstract
A surgical staple is disclosed. The staple can define a seamless unitary piece. In various instances, the staple can be formed and/or stamped from a sheet of material. The staple can include a base and staple legs. A staple drive surface can be integrally formed in the base, and a sled can directly contact the staple drive surface to directly drive the staple.
