Abstract

A staple cartridge comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises an uncompressed height, a compressed height, an outer encasement, and tubular structures aligned along the longitudinal axis. The tubular structures are configured to collapse when pressure is applied to the tissue thickness compensator by tissue during the firing motion.
