Abstract

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.

Claims

1. A staple cartridge, comprising:

a plurality of staples, wherein each said staple comprises;

a base; and

a staple leg extending from said base; and

an 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; and

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.

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.

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.
