18 Claims

1. A staple cartridge assembly, comprising:

a staple cartridge, comprising:

a cartridge deck;

staple cavities; and

a plurality of staples stored in said staple cavities, wherein said staples are deformable to a formed height during a progressive firing motion;

a tissue thickness compensator positionable on said cartridge deck, comprising:

a first fibrous, woven material; and

a second fibrous, woven material, wherein said second fibrous, woven material is different than said first fibrous, woven material, wherein said first fibrous, woven material comprises a first density and said second fibrous, woven material comprises a second density which is different than said first density, wherein said tissue thickness compensator is configured to expand upon contact with a fluid in order to apply a compressive force to tissue captured within said staples as a result of said progressive firing motion, wherein said first fibrous, woven material and said second fibrous, woven material each comprise a haemostatic agent, and wherein said haemostatic agents are configured to interact with one another in order to induce a biological response in tissue captured within said staples, wherein said tissue thickness compensator comprises an initial height before said tissue thickness compensator is captured within said staples, wherein said initial height is greater than said formed height of said staples.
