Abstract

A surgical stapling system comprising a first staple, a second staple, and a bridge connecting the first staple and the second staple. In at least one embodiment, the first staple and the second staple are part of a strip of staples. For example, the first and second staples can be included in a strip of staples that includes several staples that are attached end-to-end and/or attached side-by side. In use, the strip, or strips, of staples are inserted into a stapler which can be used to insert the staples into soft tissue, for example, and deform at least a portion of the staples to hold the tissue, or several layers of tissue, together.
