A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.

The staple cartridge of claim 7, further comprising: a plurality of staple drivers configured to move said staples between their unfired positions and their fired positions; anda sled configured to traverse said cartridge body and lift said staple drivers. 10. The staple cartridge of claim 1, wherein said uncompressed height of said tissue thickness compensator is 10 percent larger than the largest of said different compressed heights. 11. The staple cartridge of claim 1, further comprising: a plurality of staple drivers configured to move said staples between their unfired positions and their fired positions; anda sled configured to traverse said cartridge body and lift said staple drivers. 12. The staple cartridge of claim 11, wherein said uncompressed height of said tissue thickness compensator is less than 100 times larger than the largest of said different compressed heights. 13. A staple cartridge, comprising: a cartridge body comprising a plurality of staple cavities;a plurality of staples, wherein at least a portion of each said staple is removably stored within a said staple cavity, wherein each said staple is movable between an unfired position and a fired position, and wherein each said staple comprises an unfired height and a fired height; andan implantable tissue thickness compensator comprising a cartridge-facing surface, a tissue-facing surface, and a continuous portion extending between said cartridge-facing surface and said tissue-facing surface, wherein said continuous portion comprises an uncompressed height, wherein said uncompressed height is one of equal to or taller than said fired height of at least one said staple, wherein said tissue thickness compensator is comprised of an elastic material having a durometer of less than 15 Shore A and a porosity of greater than 93 percent, wherein said tissue thickness compensator is configured to be captured within said staples along with tissue, wherein said tissue thickness compensator is configured to assume different compressed heights within different said staples, and wherein said compressed height of said tissue thickness compensator within a said staple is dependent on the thickness of tissue and the durometer and the porosity of said elastic material captured within said same staple. 14. The staple cartridge of claim 13, wherein said uncompressed height of said tissue thickness compensator is taller than said fired height of said staples and shorter than twice said fired height of said staples. 15. The staple cartridge of claim 13, wherein said uncompressed height of said tissue thickness compensator is taller than said fired height of said staples and three times said fired height of said staples. 16. The staple cartridge of claim 13, wherein said uncompressed height of said tissue thickness compensator is taller than said fired height of said staples and four times said fired height of said staples. 17. The staple cartridge of claim 13, wherein said uncompressed height of said tissue thickness compensator is at least 50 percent larger than the largest of said different compressed heights. 18. A staple cartridge, comprising: a cartridge body comprising a plurality of staple cavities;a plurality of staples, wherein at least a portion of each said staple is removably stored within a said staple cavity, wherein each said staple is movable between an unfired position and a fired position, and wherein each said staple comprises an unfired height and a fired height; andan implantable tissue thickness compensator comprising a cartridge-facing surface, a tissue-facing surface, and a continuous portion extending between said cartridge-facing surface and said tissue-facing surface, wherein said continuous portion comprises an uncompressed height, wherein said uncompressed height is one of equal to or taller than said fired height of at least one said staple, wherein said tissue thickness compensator is comprised of a porous material having a porosity of at least 85 percent, wherein said tissue thickness compensator is configured to be captured within said staples, wherein said tissue thickness compensator is configured to assume different compressed heights within different said staples, and wherein said compressed height of said tissue thickness compensator within a said staple is dependent on the thickness of tissue and the porosity of said porous material captured within said same staple. 19.
