Abstract

A staple having a crown and first and second deformable members extending from the crown. In at least one embodiment, the staple further includes a base connecting the first and second deformable members where the base is not entirely co-planar with the first and second deformable members. In these embodiments, the crown can be overmolded onto, or attached to, the base and provide a larger and/or more stable tissue-contacting surface for supporting the tissue captured by the staple. As a result, the possibility of the staple being pulled through the tissue and/or the tissue tearing within or around the staple is reduced.

Claims

1. A surgical staple, comprising:

a first deformable member;

a second deformable member; and

a base connecting said first deformable member and said second deformable member, said base having a first portion and a second portion, said first portion extending transversely to said second portion.

2. The surgical staple of claim 1, wherein said base is comprised of a wire, and wherein said first portion and said second portion define portions of said wire.

3. The surgical staple of claim 1, wherein said staple further includes a crown attached to said base.

4. The surgical staple of claim 3, wherein said crown is overmolded onto said base.

5. The surgical staple of claim 3, wherein said crown is connected to a crown of a second staple, said second staple further including:

a first deformable member;

a second deformable member; and

a base connecting said first deformable member and said second deformable member, said base having a first portion and a second portion, said first portion extending transversely to said second portion.

6. The surgical staple of claim 3, wherein said crown is comprised of a bioabsorbable material.

7. The surgical staple of claim 3, wherein said crown includes a tissue-contacting surface, and wherein said first deformable member and said second deformable member are configured to capture tissue intermediate said tissue-contacting surface and said first and second deformable members.

8. The surgical staple of claim 3, wherein said staple further includes a driver attached to said crown, said driver having a cam-contacting surface configured to operatively engage with a cam of a stapler.

9. The surgical staple of claim 1, wherein said first portion extends at an approximately 90 degree angle to said second portion.

10. A surgical staple, comprising:

a first deformable member;

a second deformable member, said first member and said second member defining a plane; and

a base, wherein said first member, said second member, and said base are comprised of a wire, and wherein at least a portion of said base extends transversely to said plane.

11. The surgical staple of claim 10, wherein said staple further includes a crown attached to said base.

12. The surgical staple of claim 11, wherein said crown is overmolded onto said base.

13. The surgical staple of claim 11, wherein said crown is connected to a crown of a second staple, said second staple further including:

a first deformable member;

a second deformable member; and

a base connecting said first deformable member and said second deformable member, said base having a first portion and a second portion, said first portion extending transversely to said second portion.

14. The surgical staple of claim 11, wherein said crown is comprised of a bioabsorbable material.

15. The surgical staple of claim 11, wherein said crown includes a tissue-contacting surface, and wherein said first deformable member and said second deformable member are configured to capture tissue intermediate said tissue-contacting surface and said first and second deformable members.

16. The surgical staple of claim 11, wherein said staple further includes a driver attached to said crown, said driver having a cam-contacting surface configured to operatively engage with a cam of a stapler.

17. The surgical staple of claim 10, wherein said base includes a first portion and a second portion, and wherein said first portion extends at an approximately 90 degree angle to said second portion.

18. A surgical staple assembly, comprising:

a first staple having a first leg and a second leg;

a second staple having a first leg and a second leg, said first leg of said first staple and said first leg of said second staple defining a plane therebetween, wherein said second leg of said first staple is offset from said plane; and

a crown connecting said first staple and said second staple.

19. The surgical staple assembly of claim 18, wherein said crown includes a tissue-contacting surface configured to apply a compressive force against tissue when said first staple and said second staple have been deployed into said tissue.

20. The surgical staple assembly of claim 18, wherein said second leg of said second staple is offset from said plane.

21. A surgical stapling assembly, comprising:

a first staple having a first leg and a second leg;

a second staple having a first leg and a second leg; and

a staple cartridge having a first cavity configured for receiving said first staple and a second cavity configured for receiving said second staple, said staple cartridge having a proximal end and a distal end, wherein said first cavity is configured such that said first leg of said first staple is positioned distal with respect to said second leg of said first staple when said first staple is positioned in said first cavity, and wherein said second cavity is configured such that said first leg of said second staple is positioned distal with respect to said second leg when said second staple is positioned in said second cavity.

22. The surgical stapling system of claim 21, wherein said first leg of said first staple is positioned distal with respect to said first leg of said second staple when said first staple is positioned in said first cavity and said second staple is positioned in said second cavity.

23. The surgical stapling system of claim 21, wherein said first staple is connected to said second staple such that said first leg and said second leg of said first staple are co-planar with a plane defined between said first leg and said second leg of said second staple.
