Abstract

A surgical fastener for use in surgical procedures comprises a first member, a second member, and an anchor. Surgical materials may be secured within the surgical fastener. Methods of securing the surgical fastener to an anatomical structure are disclosed herein.

Claims

1. A method for securing a surgical material to an anatomical structure comprising the steps of:

(a) providing a surgical fastener, said surgical fastener comprising

a proximal end and a distal end;

a first member comprising, a first interior face, a first exterior face, and a first engagement element projecting from said first interior face at a first location between proximal and distal ends of said first interior face;

a second member comprising a second interior face, a second exterior face, and a second engagement element at a location between proximal and distal ends of said second interior face, said second engagement element being complementary to and aligned with said first engagement element, wherein said first engagement element interfits into said second engagement element to position said first interior face of said first member and said second interior face of said second member in proximity to each other; and

an anchor projecting from said first exterior face at a second location, said second location being different from and not axially aligned with said first location of said first engagement member;

(b) securing said surgical fastener to a surgical material;

(c) releasably attaching a surgical implantation device to said surgical fastener;

(d) introducing said surgical fastener to an implantation site in a patient'"'"'s body; and

(e) anchoring said anchor into said anatomical structure.

2. The method of claim 1, wherein said anchor is integral to said first member.

3. The method of claim 1, wherein said anchor comprises a tapered head connected to a shank.

4. The method of claim 3, wherein said shank is attached to said first member.

5. The method of claim 1, wherein said anchor is adapted to secure to an anatomical structure selected from the group consisting of bone, cartilage, tissue, muscle, and ligament.

6. The method of claim 1, wherein said surgical fastener comprises a plurality of first engagement elements and a plurality of second engagement elements.

7. The method of claim 1,

wherein said first engagement element comprises one or more pins positioned on said interior face of said first member;

and

said second engagement element is configured to couple with said pins positioned on said first member.

8. The method of claim 7, wherein said second engagement element comprises said second member defining an aperture.

9. The method of claim 1 wherein said second member further comprises one or more pins positioned on said interior face of said second member and said first member defines an aperture configured to couple with said pins positioned on said second member.

10. The method of claim 1, wherein said surgical material is selected from the group consisting of slings, sutures, meshes, yarns, tapes, threads, grafts, fabrics, and sheaths.
