Abstract

A surgical staple including a crown and a deformable member extending from the crown, the deformable member having a notch configured to cause the deformable member to bend at the notch when the staple is deformed from a first shape into a second shape. The crown of the surgical staple, in various embodiments, further includes a forming surface, or anvil, which is configured to deform the deformable member and/or guide a distal end of the deformable member when the distal end contacts the crown.

Claims

1-17. -17. (canceled)

18. A staple cartridge, comprising:

a cartridge body;

a surgical staple, wherein said surgical staple is movable from an unfired position to a fired position, wherein said surgical staple is deformable from a first shape in said unfired position to a second shape in said fired position, wherein said surgical staple comprises;

a crown; and

a first deformable member extending from said crown; and

a compressible member positioned intermediate said first deformable member and said crown after said staple has been deformed into said second shape, wherein said compressible member is at least partially positioned within said surgical staple when said surgical staple is in said unfired position.

19. The staple cartridge of claim 18, wherein said compressible member is comprised of foam.

20. The staple cartridge of claim 18, further comprising a firing member configured to translate within said cartridge body to move said surgical staple from said unfired position to said fired position.

21. The staple cartridge of claim 18, wherein said compressible member is configured to bias tissue positioned intermediate said compressible member and said first deformable member against said first deformable member.

22. The staple cartridge of claim 21, wherein said surgical staple further includes a second deformable member extending from said crown, said compressible member configured to bias the tissue against said second deformable member.

23. The staple cartridge of claim 18, wherein at least one of said compressible member and said crown are comprised of a bioabsorbable material.

24. The staple cartridge of claim 18, further comprising a firing member configured to translate within said cartridge body relative to said surgical staple to at least partially eject said surgical staple from said cartridge body.

25. A staple cartridge, comprising:

a cartridge body;

a surgical staple, wherein said surgical staple is movable from an undeployed position to a deployed position, wherein said surgical staple is deformable from a first shape in said undeployed position to a second shape in said deployed position, wherein said surgical staple comprises;

a crown; and

a first deformable member extending from said crown; and

a compressible member positioned intermediate said first deformable member and said crown after said staple has been deformed into said second shape, wherein said compressible member is at least partially housed within said surgical staple when said surgical staple is in said undeployed position.

26. The staple cartridge of claim 25, wherein said compressible member is comprised of foam.

27. The staple cartridge of claim 25, further comprising a firing member configured to translate within said cartridge body to move said surgical staple from said undeployed position to said deployed position.

28. The staple cartridge of claim 25, wherein said compressible member is configured to bias tissue positioned intermediate said compressible member and said first deformable member against said first deformable member.

29. The staple cartridge of claim 28, wherein said surgical staple further includes a second deformable member extending from said crown, said compressible member configured to bias the tissue against said second deformable member.

30. The staple cartridge of claim 25, wherein at least one of said compressible member and said crown are comprised of a bioabsorbable material.

31. The staple cartridge of claim 25, further comprising a firing member configured to translate within said cartridge body relative to said surgical staple to at least partially eject said surgical staple from said cartridge body.

32. A surgical stapling instrument, comprising:

an anvil;

a staple cartridge, wherein at least one of said anvil and said staple cartridge is movable to capture tissue between said anvil and said staple cartridge, and wherein said staple cartridge comprises;

a cartridge body; and

a surgical staple, wherein said surgical staple is movable from an undeployed position to a deployed position, wherein said surgical staple is deformable between a first shape in said undeployed position and a second shape in said deployed position, wherein said surgical staple comprises;

a crown; and

a first deformable member extending from said crown;

a firing member movable from a starting position to motivate said surgical staple to move from said undeployed position to said deployed position; and

a compressible member positioned intermediate said first deformable member and said crown after said staple has been deformed into said second shape, wherein said compressible member is at least partially housed within said surgical staple when said firing member is in said starting position.

33. The surgical stapling instrument of claim 32, wherein said compressible member is comprised of foam.

34. The surgical stapling instrument of claim 32, wherein said compressible member is configured to bias tissue positioned intermediate said compressible member and said first deformable member against said first deformable member.

35. The surgical stapling instrument of claim 34, wherein said surgical staple further includes a second deformable member extending from said crown, said compressible member configured to bias the tissue against said second deformable member.

36. The surgical stapling instrument of claim 32, wherein at least one of said compressible member and said crown are comprised of a bioabsorbable material.
