Abstract

A layer of material for use with a surgical staple cartridge is disclosed. The layer can be releasably secured to the cartridge body of the surgical staple cartridge. The layer can comprise an array of discrete distressed regions arranged in a pattern that matches a pattern of staple cavities defined in the cartridge body.

Claims

1. A staple cartridge, comprising:

a cartridge body comprising a plurality of staple cavities arranged in a pattern;

a plurality of staples removably positioned in the staple cavities; and

a layer of material releasably secured to the cartridge body, wherein the layer of material comprises a plurality of staple zones, wherein the plurality of staple zones comprises an array of discrete distressed regions, wherein the plurality of staple zones is arranged in a pattern which corresponds to the pattern of staple cavities, wherein the discrete distressed regions correspond in shape and size to the staple cavities, and wherein the discrete distressed regions directly align with the staple cavities.

2. A staple cartridge, comprising:

a cartridge body comprising a plurality of staple cavities;

a plurality of staples removably positioned in the staple cavities; and

a layer releasably secured relative to the cartridge body, wherein the layer comprises;

a first zone comprising a first stiffness;

a second zone comprising a second stiffness; and

a region intermediate the first zone and the second zone, wherein the region comprises a third stiffness, and wherein the third stiffness is less than the first stiffness and the second stiffness, and wherein the first zone and the second zone align with the staple cavities.

3. The staple cartridge of claim 2, wherein the first zone comprises a longitudinal zone, and wherein the longitudinal zone overlies a row of staple cavities.

4. The staple cartridge of claim 3, wherein the region comprises a longitudinal region adjacent to the longitudinal zone.

5. The staple cartridge of claim 2, wherein the layer comprises a flexible film, and wherein the first zone comprises an inflexible layer attached to the flexible film.

6. The staple cartridge of claim 2, wherein the first zone overlies a first staple cavity, and wherein the second zone overlies a second staple cavity.

7. The staple cartridge of claim 2, wherein the first zone is surrounded by the region.

8. The staple cartridge of claim 7, wherein the second zone is surrounded by the region.

9. The staple cartridge of claim 2, wherein the layer is comprised of a material, and wherein the material in the first zone and in the second zone is permanently-compressed.

10. The staple cartridge of claim 9, wherein the material in the region is uncompressed.

11. The staple cartridge of claim 2, wherein the first zone and the second zone comprise heat-treated zones.

12. The staple cartridge of claim 2, wherein the first stiffness and the second stiffness are equivalent.

13. A staple cartridge, comprising:

a cartridge body comprising a plurality of staple cavities;

a plurality of staples removably positioned in the staple cavities; and

an adjunct releasably secured to the cartridge body, wherein the adjunct is comprised of a material, and wherein the adjunct comprises a plurality of staple zones, wherein the staple zones comprise discrete zones in which the material is permanently-compressed to create an indent within the adjunct, and wherein the discrete zones are positioned in the adjunct to directly align with the position of the staple cavities in the cartridge body.

14. The staple cartridge of claim 13, wherein the material in each discrete zone is heat-pressed.

15. The staple cartridge of claim 13, wherein each discrete zone overlies at least one staple cavity.

16. The staple cartridge of claim 13, wherein the material comprises a first stiffness when permanently-compressed, wherein the material comprises a second stiffness when uncompressed, and wherein the second stiffness is less than the first stiffness.

17. A staple cartridge, comprising:

a cartridge body comprising a plurality of staple cavities;

a plurality of staples removably positioned in the staple cavities; and

a layer releasably secured relative to the cartridge body, wherein the layer is comprised of a material, and wherein the layer comprises;

a plurality of staple penetration zones, wherein the material in the staple penetration zones comprises a first density, and wherein the staple penetration zones align with the staple cavities in the cartridge body; and

a plurality of regions intermediate at least two staple penetration zones, wherein the material in the regions comprises a second density, and wherein the second density is different than the first density.

18. The staple cartridge of claim 17, wherein the material in each staple penetration zone is permanently-compressed.

19. The staple cartridge of claim 17, wherein the material in each staple penetration zone is heat-pressed.

20. The staple cartridge of claim 17, wherein the layer is comprised of a nonwoven material.

21. The staple cartridge of claim 17, wherein the first density is greater than the second density.
