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. A surgical staple deformable between a first shape and a second plastically-deformed shape, said staple comprising:

a base;

a crown overmolded onto said base, wherein said crown includes a staple-forming pocket; and

a first deformable member extending from said crown, said first deformable member having a first notch therein and a tip, said first notch configured to cause said deformable member to bend at said first notch when said staple is deformed from said first shape into said second plastically-deformed shape, said staple-forming pocket comprising a forming surface configured to receive said tip and plastically deform said deformable member when said deformable member contacts said crown.

2. The surgical staple of claim 1, wherein said first deformable member has a second notch therein, said second notch configured to cause said deformable member to bend at said second notch when said staple is deformed from said first shape into said second shape.

3. The surgical staple of claim 1, wherein said first notch is tapered and circumscribes said first deformable member.

4. The surgical staple of claim 1, wherein said crown is comprised of a bioabsorbable material.

5. The surgical staple of claim 1, wherein said crown comprises a side, and wherein said staple-forming pocket comprises a recess in said side of said crown.

6. The surgical staple of claim 1, wherein said forming surface comprises a bottom of said staple-forming pocket.

7. The surgical staple of claim 1, wherein said deformable member consists of an elongate metal wire.

8. The surgical staple of claim 1, further comprising a second deformable member extending from said crown, wherein said second deformable member comprises a second tip, wherein said crown includes a second staple-forming pocket;

said second staple-forming pocket comprising a second forming surface configured to receive said second tip and plastically deform said second deformable member when said second deformable member contacts said crown.

9. A surgical staple deformable between a first shape and a second plastically-deformed shape, said staple comprising:

a crown, said crown including a forming surface; and

a first deformable member extending from said crown, said forming surface configured to plastically deform said first deformable member when said staple is deformed from said first shape into said second plastically-deformed shape.

10. The surgical staple of claim 9, wherein said first deformable member includes an elongate metal wire having at least one notch therein, said notch configured to cause said deformable member to bend at said notch when said staple is deformed between said first shape and said second shape.

11. The surgical staple of claim 9, wherein said crown is comprised of a bioabsorbable material.

12. The surgical staple of claim 9, wherein said crown comprises a side, and wherein said forming surface comprises a recess in said side of said crown.

13. The surgical staple of claim 9, wherein said forming surface comprises a bottom of a staple-forming pocket.

14. The surgical staple of claim 9, further comprising a second deformable member extending from said crown, wherein said crown includes a second forming surface configured to plastically deform said second deformable member when said second staple is deformed from said first shape into said second plastically-deformed shape.

24. A surgical stapling system, comprising:

a staple, said staple including a deformable member; and

a stapling instrument, including;

a staple cartridge; and

first forming means for deforming said deformable member between a first shape and a second plastically-deformed shape;

at least one of said staple and said staple cartridge further including second forming means for co-operating with said first forming means to deform said deformable member between said plastically-deformed second shape and a third plastically-deformed shape.

25. The surgical stapling system of claim 24, wherein said deformable member includes a first notch therein, said first notch configured to cause said deformable member to bend at said first notch when said deformable member is deformed between said first shape and said second shape.
