Abstract
An anvil assembly is provided and includes an anvil member having a plurality of staple bending pockets formed in a face of the anvil member and a length of reinforcing material suspended across the staple bending pockets. Longitudinal channels are provided in the face of the anvil member to releasably retain the reinforcing material. The longitudinal channels transect the staple bending pockets and support and suspend the reinforcing material over the staple bending pockets such that a leg of a surgical staple can be bent around the reinforcing material. Various configurations of fully formed staples are also disclosed and include a backspan having first and second legs extending from the backspan. First portions of each of the first and legs extend from the backspan and define a plane with the backspan. Second portions of each of the first and second legs extend from the first portions and project outwardly from the plane defined by the backspan and the first second portions.
