A fastener cartridge can comprise a compressible, collapsible, and/or crushable cartridge body and fasteners embedded within the cartridge body 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 the first jaw can be positioned opposite a second jaw, or anvil. The anvil can be engaged with the fastener cartridge to compress, collapse, and/or crush the cartridge body and deform, or otherwise deploy, the fasteners contained therein. As the fasteners are deformed or deployed, the fasteners can capture at least a portion of the cartridge body therein along with at least a portion of the tissue being fastened. In various embodiments, the cartridge body can comprise a plurality of bioabsorbable layers. These bioabsorbable layers can be comprised of materials which can be bioabsorbed at different rates.
1. A staple cartridge, comprising: a plurality of staples, wherein each said staple comprises: a base; anda staple leg extending from said base; andan implantable staple cartridge body supporting said plurality of staples, wherein each said base is embedded in said implantable staple cartridge body
1. A staple cartridge, comprising: a plurality of staples, wherein each said staple comprises: a base; anda staple leg extending from said base; andan implantable staple cartridge body supporting said plurality of staples, wherein each said base is embedded in said implantable staple cartridge body and is moveable relative to said implantable staple cartridge body, and wherein said implantable staple cartridge body comprises: a first layer comprised of a first material; anda second layer comprised of a second material, wherein said first material is bioabsorbable at a first rate and said second material is bioabsorbable at a second rate, and wherein said first rate is different than said second rate. 2. The staple cartridge of claim 1, wherein said first layer is encapsulated in said second layer. 3. The staple cartridge of claim 1, wherein said first layer of said implantable staple cartridge body comprises a plurality of voids, and wherein a medicament is positioned within said voids. 4. The staple cartridge of claim 1, wherein said implantable staple cartridge body further comprises a third layer comprised of a third material, and wherein said third material is bioabsorbable at a third rate which is different than said first rate and said second rate. 5. The staple cartridge of claim 1, wherein said first material comprises a hemostatic material, and wherein said second material comprises a buttress material. 6. The staple cartridge of claim 5, wherein said buttress material comprises a tissue-contacting surface, wherein said buttress material is adhered to a first side of said hemostatic material, and wherein said implantable staple cartridge body further comprises a third layer comprised of a buttress material adhered to a second side of said hemostatic material. 7. The staple cartridge of claim 6, wherein said implantable staple cartridge body further comprises a fourth layer comprised of a hemostatic material adhered to said third layer. 8. The staple cartridge of claim 7, wherein each said staple leg extends through said fourth layer, said third layer, and said second layer. 9. The staple cartridge of claim 1, wherein said first layer is collapsible. 10. A fastener cartridge, comprising: a plurality of fasteners; andan implantable cartridge body, wherein said fasteners are encapsulated and sealed in said implantable cartridge body, and wherein said implantable cartridge body comprises: a first laminate comprised of a first material; anda second laminate comprised of a second material, wherein said first material is dissolvable at a first rate and said second material is dissolvable at a second rate, and wherein said first rate is different than said second rate. 11. The fastener cartridge of claim 10, wherein said first laminate is encapsulated in said second laminate. 12. The fastener cartridge of claim 10, wherein said first laminate of said implantable cartridge body comprises a plurality of voids, and wherein a medicament is positioned within said voids. 13. The fastener cartridge of claim 10, wherein said implantable cartridge body comprises a third laminate comprised of a third material, and wherein said third material is bioabsorbable at a third rate which is different than said first rate and said second rate. 14. The fastener cartridge of claim 10, wherein said first material comprises a hemostatic material, and wherein said second material comprises a buttress material. 15. The fastener cartridge of claim 14, wherein said buttress material comprises a tissue-contacting surface, wherein said buttress material is adhered to a first side of said hemostatic material, and wherein said implantable cartridge body further comprises a third laminate comprised of a buttress material adhered to a second side of said hemostatic material. 16. The fastener cartridge of claim 15, wherein said implantable cartridge body further comprises a fourth laminate comprised of a hemostatic material adhered to said third laminate. 17. The fastener cartridge of claim 16, wherein each said fastener comprises a base and a leg, and wherein said leg extends through said fourth laminate, said third laminate, and said second laminate. 18. The fastener cartridge of claim 10, wherein said first laminate is collapsible. 19. A fastener cartridge, comprising: a plurality of fasteners; anda unitary implantable cartridge body, wherein said plurality of fasteners are moveably positioned in said unitary implantable cartridge body, and wherein said unitary implantable cartridge body comprises: means for storing said plurality of fasteners;a unitary layer of material attached to said means, wherein said means is dissolvable at a first rate and said unitary layer of material is dissolvable at a second rate, and wherein said first rate is different than said second rate; anda tissue contacting surface, wherein said fasteners are configured to move at least partially through said tissue contacting surface. 20. The staple cartridge of claim 1, wherein said base of each said staple is moveable through said implantable staple cartridge body. 21. The staple cartridge of claim 20, wherein said implantable staple cartridge body comprises a tissue contacting surface, and wherein each said staple is configured to pierce said tissue contacting surface. 22. The staple cartridge of claim 1, wherein each said staple is encapsulated in said implantable staple cartridge body. 23. The fastener cartridge of claim 10, wherein said fasteners are moveably positioned in said implantable cartridge body. 24. The fastener cartridge of claim 23, wherein said implantable cartridge body comprises a tissue contacting surface, and wherein said fasteners are configured to pierce said tissue contacting surface. 25. The fastener cartridge of claim 19, wherein said fasteners are entirely embedded in said unitary implantable cartridge body. 26. An entirely-implantable staple cartridge for use with a surgical stapler, the entirely-implantable staple cartridge comprising: a plurality of staples, wherein each said staple comprises: a base; anda leg extending from said base; andan implantable cartridge body, wherein said staples are arranged in a plurality of rows in said implantable cartridge body, and wherein said implantable cartridge body comprises: a first layer comprised of a first material;a second layer comprised of a second material, wherein said first material is bioabsorbable at a first rate and said second material is bioabsorbable at a second rate, and wherein said first rate is different than said second rate; anda tissue contacting surface, wherein said staples are configured to move in said implantable cartridge body toward said tissue contacting surface. 27.
