Abstract

A surgical stapling system comprising a first staple, a second staple, and a bridge connecting the first staple and the second staple. In at least one embodiment, the first staple and the second staple are part of a strip of staples. For example, the first and second staples can be included in a strip of staples that includes several staples that are attached end-to-end and/or attached side-by side. In use, the strip, or strips, of staples are inserted into a stapler which can be used to insert the staples into soft tissue, for example, and deform at least a portion of the staples to hold the tissue, or several layers of tissue, together.

a second stap1e, wherein said second staple comprises;

a second deformable member;

a second base wherein said second deformable member extends from said second base; and

a second crown, wherein said second crown is attached to said second base, wherein said second crown includes a second tissue-contacting surface, and wherein, upon deployment, said second deformable member is configured to capture tissue intermediate said second deformable member and said second tissue-contracting surface; and

a bridge connecting said first crown to said second crown, wherein said bridge is configured to be deployed with at least one of said first staple and said second staple when said first and second staples are deployed.

3. The surgical stapling system of claim 1, wherein at least a portion of said bridge is flexible such that said first staple is not detached from said second staple when said first staple is deployed.

4. The surgical stapling system of claim 1, wherein at least a portion of said bridge is frangible such that said first staple detaches from said second staple when said first staple is deployed.

5. The surgical stapling system of claim 1, wherein at least a portion of said bridge is comprised of a bioabsorbable material.

24. The surgical stapling system of claim 1, wherein said first and second crowns are comprised of a metal material, and wherein said first and second deformable members are comprised of a non-metal material.

25. The surgical stapling system of claim 24, wherein said first crown is overmolded onto said first base, and wherein said second crown is overmolded onto said second base.

2. (canceled)

6. A surgical stapling system for stapling tissue, comprising:

a first staple, wherein said first staple comprises;

a first deformable member;

a first base, wherein said first deformable member extends from said first base; and

a first crown, wherein said first crown is attached to said first base, wherein said first crown includes a first tissue-contacting surface, and wherein, upon deployment, said first deformable member is configured to capture tissue intermediate said first deformable member and said first tissue-contacting surface;

a second staple, wherein said second staple comprises;

a second deformable member;

a second base, wherein said second deformable member extends from said second base; and

a second crown, wherein said second crown is attached to said base, wherein said second crown includes a second tissue-contacting surface, and wherein, upon deployment, said second deformable member is configured to capture tissue intermediate said second deformable member and said second tissue-contracting and

connection means for connecting said first crown and said second crown.

8. The surgical stapling system of claim 6, wherein at least a portion of said connection means is flexible such that said first staple is not detached from said second staple when said first staple is deployed.

9. The surgical stapling system of claim 6, wherein at least a portion of said connection means is frangible such that said first staple detaches from said second staple when said first staple is deployed.

10. The surgical stapling system of claim 6, wherein at least a portion of said bridge is comprised of a bioabsorbable material.
