Tissue thickness compensators for use with circular surgical staplers. Various tissue thickness compensators are disclosed for deployment between a stapler head of a surgical circular stapler and an anvil attached thereto to accommodate variances in tissue thickness during stapling. Some tissue thickness compensator arrangements include means and configurations for deploying healing agents for enhancing the healing process.
1. A tissue thickness compensator for use with a circular surgical stapler including a staple cartridge with a cartridge deck and an anvil movably supported relative to the staple cartridge such that a staple forming surface of the anvil is in confronting relationship relative to the cartridge deck
1. A tissue thickness compensator for use with a circular surgical stapler including a staple cartridge with a cartridge deck and an anvil movably supported relative to the staple cartridge such that a staple forming surface of the anvil is in confronting relationship relative to the cartridge deck and a tissue cutting member axially advanceable out of the staple cartridge toward the anvil, the tissue thickness compensator comprising: a compressible, bioabsorbable annular body member configured to be supported between the staple forming surface and the cartridge deck; andan attachment tab protruding from the compressible body member and configured for attachment to the anvil to retain the compressible body member between the staple forming surface and the cartridge deck. 2. A tissue thickness compensator for use with a circular surgical stapler including an elongated shaft that includes a stapler head that supports a surgical staple cartridge therein and an anvil including an anvil body and an anvil shaft that is removably attachable to the stapler head, the tissue thickness compensator comprising: an annular compressible bioabsorbable body member;an attachment member coupled to the compressible body member and configured for retaining engagement with the stapler head to support the compressible body member between the staple cartridge and the anvil body; andan introducer comprising: an elongated sheath configured to receive the elongated shaft and the stapler head therein, the elongated sheath including a distal end configured to support the tissue thickness compensator therein for seating engagement with the stapler head; anda releasable cap on the distal end of the elongated sheath, the releasable cap movable from a closed position to an open position wherein the stapler head and the tissue thickness compensator are advanceable out through the distal end of the sheath. 3. A tissue thickness compensator for use with a circular surgical stapler that comprises a staple cartridge and an anvil, the tissue thickness compensator comprising: a compressible body portion comprising an annular perimeter; andan attachment member coupled to the compressible body portion and configured for attachment to the anvil to retain the compressible body portion between the staple cartridge and the anvil, wherein the attachment member comprises a cushion extending at least partially around the annular perimeter of the compressible body portion. 4. A tissue thickness compensator for use with a circular surgical stapler including a staple cartridge with a cartridge deck and an anvil movably supported relative to the staple cartridge such that a staple forming surface of the anvil is in confronting relationship relative to the cartridge deck and a tissue cutting member axially advanceable out of the staple cartridge toward the anvil, the tissue thickness compensator comprising: a compressible, bioabsorbable annular body member configured to be supported between the staple forming surface and the cartridge deck; andan attachment member coupled to the compressible body member and configured for attachment to the anvil to retain the compressible body member between the staple forming surface and the cartridge deck, wherein the attachment member comprises a hood extending over a distal end of the anvil and attached to the compressible body member such that the compressible body member is retained adjacent to the staple forming surface, wherein the hood is movably attached to the anvil, and wherein the compressible body portion includes at least one side wall and wherein the hood is movable from a neutral position wherein the hood covers the at least one side wall to a deployed position wherein the at least one side wall is uncovered. 5. The tissue thickness compensator of claim 4 wherein the hood is biased into the neutral position. 6. A tissue thickness compensator for use with a circular surgical stapler including a staple cartridge with a cartridge deck and an anvil movably supported relative to the staple cartridge such that a staple forming surface of the anvil is in confronting relationship relative to the cartridge deck and a tissue cutting member axially advanceable out of the staple cartridge toward the anvil, the tissue thickness compensator comprising: a compressible, bioabsorbable annular body member configured to be supported between the staple forming surface and the cartridge deck; andan attachment member coupled to the compressible body member and configured for attachment to the anvil to retain the compressible body member between the staple forming surface and the cartridge deck, wherein the attachment member comprises a deformable bead attached to the compressible body member. 7. The tissue thickness compensator of claim 6 wherein the deformable bead extends around a perimeter of the compressible body member. 8. The tissue thickness compensator of claim 6 wherein the deformable bead is constructed from a burstable material. 9. The tissue thickness compensator of claim 8 wherein the deformable bead contains a liquid material. 10. The tissue thickness compensator of claim 9 wherein the liquid material is selected from the group of liquid materials consisting of a saline liquid, a liquid healing agent and an anti-microbial liquid. 11. A surgical instrument assembly, comprising: a circular surgical stapler, comprising: a staple cartridge;a plurality of staples removably stored in the staple cartridge; andan anvil configured to deform the staples; anda tissue thickness compensator, comprising: a compressible body portion comprising an annular perimeter; andan attachment tab protruding from the compressible body portion, wherein the attachment tab is attached to the anvil to releasably retain the compressible body portion between the anvil and the staple cartridge. 12. The surgical instrument assembly of claim 11, wherein the tissue thickness compensator comprises silver. 13. A surgical stapling assembly, comprising: a circular surgical stapler, comprising: a staple cartridge;a plurality of staples removably stored in the staple cartridge; andan anvil positionable relative to the staple cartridge; anda tissue thickness compensator comprising a circular periphery, the tissue thickness compensator comprising: a compressible body supported between the anvil and the staple cartridge; andan attachment extending from the compressible body member which holds the compressible body between the anvil and the staple cartridge. 14. The surgical stapling assembly of claim 13, wherein the tissue thickness compensator comprises silver.
