Abstract

A staple cartridge assembly comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises a first fibrous, woven material and a second fibrous, woven material. The first fibrous, woven material comprises a density which is different than the density of the second fibrous, woven material. The tissue thickness compensator is configured to expand upon contact with a fluid in order to apply a compressive force to tissue captured within staples.
