Abstract

A fastener cartridge assembly for stapling tissue includes a staple cartridge, fashioned to drive staples through tissue, a plurality of staples and a tissue thickness compensator assembly. The tissue thickness compensator is comprised of a sacrificial compressible layer and a resilient compressible layer. The sacrificial compressible layer is designed such that the resilient compressible layer compresses more easily at low pressures, but the sacrificial compressible layer compresses more easily at high pressures. The resilient compressible layer ensures that thin tissue is compressed when the staples are ejected into the tissue while the sacrificial compressible layer prevents over compression of the tissue. The tissue thickness compensator assembly can therefore be designed to provide a specific deflection-compression curve.
