In various embodiments, a compensator can be attachable to an anvil of a fastening instrument. The compensator can comprise a support layer configured to be attached to the anvil and a scaffold attached to the support layer. In at least one embodiment, the scaffold can comprise a plurality of scaffold layers comprised of a biocompatible material and a plurality of cavities, wherein the layers and the cavities can define a matrix favorable to tissue and cellular ingrowth.
1. A compensator attachable to an anvil of a fastening instrument, wherein the anvil includes a forming surface and a longitudinal slot configured to receive a cutting member, wherein the cutting member is configured to travel between a proximal end and a distal end of the anvil, wherein the forming
1. A compensator attachable to an anvil of a fastening instrument, wherein the anvil includes a forming surface and a longitudinal slot configured to receive a cutting member, wherein the cutting member is configured to travel between a proximal end and a distal end of the anvil, wherein the forming surface is configured to deform a plurality of fasteners to fasten tissue, and wherein said compensator comprises: a support layer configured to be attached to the anvil;a scaffold attached to said support layer, said scaffold comprising: a plurality of collapsible scaffold layers comprised of a biocompatible material, said collapsible scaffold layers comprising: a first layer comprising a first pattern of fibers oriented in a direction at least substantially parallel to said longitudinal slot and extending between the proximal end and the distal end of the anvil; anda second layer comprising a second pattern of fibers interwoven with said first layer; anda plurality of cavities, wherein said support layer, said scaffold layers, and said cavities define a matrix favorable to tissue and cellular ingrowth, and wherein said collapsible scaffold layers are configured to adapt to the thickness of tissue captured within the fasteners. 2. The compensator of claim 1, wherein each said scaffold layer is comprised of a fiber weave. 3. The compensator of claim 1, wherein said direction comprises a first direction, wherein said second pattern of fibers is oriented in a second direction, and wherein said first direction is oblique to said second direction. 4. The compensator of claim 1, further comprising a medicament contained within said plurality of scaffold layers. 5. The compensator of claim 1, wherein said first layer is comprised of a first material and said second layer is comprised of a second material, and wherein said first material is different than said second material. 6. The compensator of claim 1, wherein a first medicament is absorbed within said first layer and a second medicament is absorbed within said second layer, and wherein said first medicament is different than said second medicament. 7. The compensator of claim 1, wherein said scaffold comprises an outer surface, and wherein each said cavity comprises an opening in said outer surface. 8. A compensator attachable to an anvil of a fastening instrument, wherein the anvil includes a forming surface configured to deform a plurality of fasteners to fasten tissue, and wherein said compensator comprises: an attachment layer configured to be attached to the anvil;a structural matrix attached to said attachment layer, said structural matrix comprising: a plurality of collapsible matrix layers comprised of biocompatible material, said collapsible matrix layers comprising: a first layer comprising a first material; anda second layer comprising a second material different than said first material; anda plurality of wells, wherein said matrix layers and said wells define a structural support favorable to tissue and cellular ingrowth, wherein said first material and said second material are configured to induce a biologic response such that tissue is encouraged toward said wells upon the interaction of said first material and said second material, and wherein said collapsible matrix layers are configured to adapt to the thickness of tissue captured within the fasteners. 9. The compensator of claim 8, wherein each said matrix layer is comprised of a fiber weave. 10. The compensator of claim 8, wherein said first layer comprises a first pattern of fibers and said second layer comprises a second pattern of fibers, and wherein said first pattern of fibers is different than said second pattern of fibers. 11. The compensator of claim 8, wherein said first layer comprises fibers oriented in a first direction, wherein said second layer comprises fibers oriented in a second direction, and wherein said first direction is oblique to said second direction. 12. The compensator of claim 8, further comprising a medicament contained within said plurality of matrix layers. 13. The compensator of claim 8, wherein said first medicament is absorbed within said first layer and said second medicament is absorbed within said second layer. 14. The compensator of claim 8, wherein said structural matrix comprises an outer surface, and wherein each said well comprises an opening in said outer surface. 15. A stapling assembly for use with a fastening instrument and is configured to deform a plurality of fasteners to fasten tissue, said stapling assembly comprising: an anvil comprising a forming surface and a longitudinal slot configured to receive a cutting member;a compensator comprising: a support layer attached to said anvil;a scaffold attached to said support layer, said scaffold comprising: a plurality of collapsible scaffold layers comprised of a biocompatible material, said collapsible scaffold layers comprising: a first layer comprising a first medicament and a first array of fibers, wherein said first array of fibers is oriented at least substantially parallel to said longitudinal slot; anda second layer comprising a second medicament and a second array of fibers;a medicament embedded in said scaffold layers; anda plurality of cavities, wherein said scaffold layers and said cavities define a matrix favorable to tissue and cellular ingrowth, wherein said first medicament and said second medicament are configured to interact with each other generating a biological reaction to encourage cellular migration into said cavities, and wherein said collapsible scaffold layers are configured to adapt to the thickness of tissue captured within the fasteners.
