A surgical end effector comprising a staple cartridge, an anvil, and a compressible portion intermediate the staple cartridge and the anvil is disclosed. The compressible portion comprises a plurality of tubular members.
1. A staple cartridge, comprising: a cartridge body, wherein a plurality of staple cavities are defined in the cartridge body;a plurality of staples removably positioned in the staple cavities; anda compressible layer releasably positioned adjacent to the cartridge body, wherein the compressible lay
1. A staple cartridge, comprising: a cartridge body, wherein a plurality of staple cavities are defined in the cartridge body;a plurality of staples removably positioned in the staple cavities; anda compressible layer releasably positioned adjacent to the cartridge body, wherein the compressible layer comprises a plurality of tubular members. 2. The staple cartridge of claim 1, wherein each of the tubular members comprises a plurality of braided strands. 3. The staple cartridge of claim 1, wherein the tubular members are comprised of a bioabsorbable material. 4. The staple cartridge of claim 1, wherein each of the tubular members comprises a central lumen, and wherein at least one therapeutic agent is positioned in each of the central lumens. 5. The staple cartridge of claim 4, wherein the at least one therapeutic agent is selected from a group consisting of fibrin, thrombin, oxidized regenerated cellulose, diclofenac, aspirin, naproxen, sulindac, hydrocortisone, triclosan, ionic silver, ampicillin, gentamicin, polymyxin B, chloramphenicol, cisplatin, mitomycin, and adriamycin, and combinations thereof. 6. The staple cartridge of claim 4, wherein the at least one therapeutic agent comprises a hydrophilic material. 7. The staple cartridge of claim 1, wherein the compressible layer further comprises a sheet of material positioned at least partially around the tubular members. 8. The staple cartridge of claim 1, wherein the compressible layer further comprises: a top layer; anda bottom layer, wherein the plurality of tubular members are positioned intermediate the top layer and the bottom layer. 9. A staple cartridge, comprising: a cartridge body, wherein a plurality of staple cavities are defined in the cartridge body;a plurality of staples removably positioned in the staple cavities; anda compressible portion releasably secured adjacent to the cartridge body, wherein the compressible portion comprises a plurality of strands woven into a tubular lattice. 10. The staple cartridge of claim 9, wherein the strands are comprised of a bioabsorbable material. 11. The staple cartridge of claim 9, wherein the tubular lattice further comprises a central lumen, and wherein at least one therapeutic agent is positioned in the central lumen. 12. The staple cartridge of claim 11, wherein the at least one therapeutic agent is selected from a group consisting of fibrin, thrombin, oxidized regenerated cellulose, diclofenac, aspirin, naproxen, sulindac, hydrocortisone, triclosan, ionic silver, ampicillin, gentamicin, polymyxin B, chloramphenicol, cisplatin, mitomycin, and adriamycin, and combinations thereof. 13. The staple cartridge of claim 11, wherein the at least one therapeutic agent comprises a hydrophilic material. 14. The staple cartridge of claim 9, wherein the compressible portion further comprises: a first portion; anda second portion, wherein the tubular lattice is positioned intermediate the first portion and the second portion. 15. The staple cartridge of claim 9, wherein the tubular lattice is deformable from an uncompressed height to at least one compressed height, and wherein the tubular lattice is configured to generate a restoring force when deformed to the at least one compressed height. 16. A surgical end effector, comprising: a staple cartridge;an anvil; anda compressible portion intermediate the staple cartridge and the anvil, wherein the compressible portion comprises a plurality of tubular members. 17. The surgical end effector of claim 16, wherein each of the tubular members further comprises a plurality of braided strands. 18. The surgical end effector of claim 16, wherein the tubular members are comprised of a bioabsorbable material. 19. The surgical end effector of claim 16, wherein the compressible portion further comprises: a first layer; anda second layer, wherein the tubular members are positioned intermediate the first layer and the second layer. 20. The surgical end effector of claim 16, wherein the tubular members comprise an uncompressed height, and wherein the tubular members are configured to generate a restoring force when deformed from the uncompressed height. 21. The surgical end effector of claim 16, wherein at least one of the tubular members is comprised of secondary tubular members.
