A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.
1. A surgical stapler, comprising: an end effector, comprising: a staple cartridge;an anvil including an inner lip and an outer lip; anda cutting member movable to cut tissue captured between said staple cartridge and said anvil; anda buttress material, wherein said buttress material is releasably r
1. A surgical stapler, comprising: an end effector, comprising: a staple cartridge;an anvil including an inner lip and an outer lip; anda cutting member movable to cut tissue captured between said staple cartridge and said anvil; anda buttress material, wherein said buttress material is releasably retained to said anvil by said inner lip and said outer lip, wherein said inner lip and said outer lip are positioned on a same side of said cutting member. 2. The surgical stapler of claim 1, wherein said staple cartridge comprises a surgical staple removably stored within said staple cartridge, wherein said surgical staple includes a deformable member. 3. The surgical stapler of claim 2, wherein said anvil further comprises at least one pocket, wherein said anvil pocket is configured to deform said deformable member, and wherein said buttress material is located between said staple cartridge and said anvil pocket. 4. The surgical stapler of claim 2, wherein said deformable member is configured to extend through said buttress material in a first direction, and wherein said deformable member is configured to engage said buttress member in a second direction after being deformed by said anvil. 5. The surgical stapler of claim 4, wherein said deformable member is configured to release said buttress material from said anvil when said deformable member engages said buttress material in said second direction. 6. The surgical stapler of claim 4, wherein said buttress material includes an aperture configured to receive said deformable member and allow said deformable member to extend therethrough in said first direction without piercing said buttress material. 7. The surgical stapler of claim 4, further comprising a second staple removably stored within said staple cartridge, wherein said second staple includes a deformable member, wherein said deformable member of said second staple is configured to extend through said buttress material in a first direction, and wherein said deformable member of said second staple is configured to engage said buttress member in a second direction after being deformed by said anvil. 8. The surgical stapler of claim 1, wherein at least one of said inner lip and said outer lip comprises a slot configured to receive said buttress material. 9. The surgical stapler of claim 1, wherein at least a portion of said buttress material is comprised of a bioabsorbable material. 10. A surgical stapler, comprising: an end effector, comprising: a staple cartridge;an anvil including a first groove and a second groove; anda cutting member movable to cut tissue captured between said staple cartridge and said anvil; anda buttress material, wherein said buttress material is releasably retained to said anvil by said first groove and said second groove, wherein said first groove and said second groove are positioned on a same side of said cutting member, and wherein said second groove is further away from said cutting member than said first groove. 11. The surgical stapler of claim 10, further comprising a surgical staple removably stored within said staple cartridge, wherein said surgical staple includes a deformable member. 12. The surgical stapler of claim 11, wherein said anvil further comprises at least one pocket, wherein said anvil pocket is configured to deform said deformable member, and wherein said buttress material is located between said staple cartridge and said anvil pocket. 13. The surgical stapler of claim 11, wherein said deformable member is configured to extend through said buttress material in a first direction, and wherein said deformable member is configured to engage said buttress material in a second direction after being deformed by said anvil. 14. The surgical stapler of claim 13, wherein said deformable member is configured to release said buttress material from said anvil when said deformable member engages said buttress material in said second direction. 15. The surgical stapler of claim 13, wherein said buttress material includes an aperture configured to receive said deformable member and allow said deformable member to extend therethrough in said first direction without piercing said buttress material. 16. The surgical stapler of claim 13, further including a second staple removably stored within said staple cartridge, wherein said second staple includes a deformable member, wherein said deformable member of said second staple is configured to extend through said buttress material in a first direction, and wherein said deformable member of said second staple is configured to engage said buttress member in a second direction after being deformed by said anvil. 17. The surgical stapler of claim 10, wherein at least a portion of said buttress material is comprised of a bioabsorbable material.
