Abstract

A fastener cartridge assembly for use with a surgical instrument is disclosed. The fastener cartridge assembly can include a cartridge body, a plurality of fasteners removably stored within the cartridge body, and an implantable layer. The fastener cartridge assembly and/or the surgical instrument can include a lockout system configured to deactivate the fastener cartridge assembly and/or surgical instrument in the event that the implantable layer is prematurely removed from the fastener cartridge.

Claims

1-26. -26. (canceled)

27. A staple cartridge assembly for use with a surgical instrument, wherein the staple cartridge assembly comprises:

a staple cartridge, comprising;

a cartridge body; and

a plurality of staples stored in the cartridge body; and

a compressible tissue thickness compensator, comprising;

a deck-facing side;

a tissue-facing side;

a first portion; and

a second portion, wherein the second portion comprises a curved depression on the tissue-facing side of the compressible tissue thickness compensator.

28. The staple cartridge assembly of claim 27, wherein the second portion comprises a different porosity than the first portion.

29. The staple cartridge assembly of claim 27, wherein the second portion comprises a different density than the first portion.

30. A staple cartridge assembly for use with a surgical instrument, wherein the staple cartridge assembly comprises:

a staple cartridge, comprising;

a cartridge body; and

a plurality of staples stored in the cartridge body; and

a compressible tissue thickness compensator, comprising;

a deck-facing side;

a tissue-facing side;

a first portion; and

a second portion, wherein the second portion comprises a groove configured to accommodate a tubular structure on the tissue-facing side of the compressible tissue thickness compensator.

31. The staple cartridge assembly of claim 30, wherein the second portion comprises a different porosity than the first portion.

32. The staple cartridge assembly of claim 30, wherein the second portion comprises a different density than the first portion.

33. A staple cartridge assembly for use with a surgical instrument, wherein the staple cartridge assembly comprises:

a staple cartridge, comprising;

a cartridge body; and

a plurality of staples stored in the cartridge body; and

a compressible tissue thickness compensator, comprising;

a deck-facing side;

a tissue-facing side;

a width;

a first portion; and

a second portion, wherein the second portion comprises an arcuate shape on the tissue-facing side, and wherein the arcuate shape extends across the entire width of the tissue thickness compensator.

34. The staple cartridge assembly of claim 33, wherein the second portion comprises a different porosity than the first portion.

35. The staple cartridge assembly of claim 33, wherein the second portion comprises a different density than the first portion.
