Abstract

A surgical device includes a member having first and second opposing surfaces. The member includes an intermediate portion in which the first surface has a recessed surface portion. The intermediate portion defines a hole extending from the recessed surface portion to the second surface. End portions extend from the intermediate portion, and each end portion defines a hole extending from the first surface to the second surface. The member has a tapered surface portion on the second surface. The surgical device includes a second member sized to be received within the recessed surface portion. A method includes locating a tissue fixation device at an opening to a bone hole, and increasing the size of the tissue fixation device by placing the tissue fixation device within a larger device.

First claim

What is claimed is:

1. A surgical device for tissue repair comprising:
a first member having first and second opposing surfaces, the first opposing surface having a non-recessed surface portion and a recessed surface portion, the recessed surface portion having a planar shape, the first member having an inner perimeter extending from the non-recessed surface portion to the recessed surface portion, the recessed surface portion and the inner perimeter defining a recessed portion, the first member defining a hole extending from the recessed surface portion to the second opposing surface, the first member further having an intermediate portion and end portions extending from the intermediate portion, wherein a gradual taper is located along the entire distance between the end portions and the intermediate portion, the gradual taper only on the second opposing surface; and
a second member defining a hole and having an outer perimeter, wherein the second member is configured to be located at an opening to a bone hole such that the second member can be received within the recessed portion of the first member with the inner perimeter of the first member adjacent to the outer perimeter of the second member, wherein a combined surface area of a surface of the second member and the non-recessed surface portion of the first opposing surface of the first member is larger than a surface area of the surface of the second member.

2. The surgical device of claim 1 , wherein the first member hole comprises an elongated hole.

3. The surgical device of claim 1 , wherein the first member hole and the second member hole are positioned to be axially aligned when the second member is received within the recessed portion.

4. The surgical device of claim 1 , wherein the recessed portion is configured to provide a snap-fit with the second member.

5. The surgical device of claim 1 , wherein the recessed portion is configured to provide an interference-fit with the second member.

6. The surgical device of claim 1 , further comprising a suture extending through the first member hole and the second member hole.

7. The surgical device of claim 1 , wherein the first member defines two additional holes.

8. The surgical device of claim 1 , wherein the second member defines three additional holes.

9. The surgical device of claim 1 , wherein the second member hole is for housing suture during the tissue repair.

10. The surgical device of claim 1 , wherein the portion of the second opposing surface opposite the recessed surface portion defines a planar surface that is substantially parallel to the first opposing surface.

11. A surgical device for tissue repair comprising:
a first member having first and second opposing surfaces, the first opposing surface having a non-recessed surface portion and a recessed surface portion, the recessed surface portion having a planar shape, the first member having an inner perimeter extending from the non-recessed surface portion to the recessed surface portion, the recessed surface portion and the inner perimeter defining a recessed portion, the first member defining a hole extending from the recessed surface portion to the second opposing surface, the first member further having an intermediate portion and end portions extending from the intermediate portion, wherein a gradual taper is located along the entire distance between the end portions and the intermediate portion, the gradual taper only on the second opposing surface; and
a second member defining a plurality of through holes for receiving one or more flexible members and having an outer perimeter, wherein the second member is configured to be received within the recessed portion of the first member with the inner perimeter of the first member adjacent to the outer perimeter of the second member, wherein a combined surface area of a surface of the second member and the non-recessed surface portion of the first opposing surface of the first member is larger than a surface area of the surface of the second member.

12. The surgical device of claim 11 , wherein the first member hole comprises an elongated hole.

13. The surgical device of claim 11 , wherein the first member hole and the plurality of second member holes are positioned to be axially aligned when the second member is received within the recessed portion.

14. The surgical device of claim 11 , wherein the recessed portion is configured to provide a snap-fit with the second member.

15. The surgical device of claim 11 , wherein the recessed portion is configured to provide an interference-fit with the second member.

16. The surgical device of claim 11 , further comprising a suture extending through the first member hole and the plurality of second member holes.

17. The surgical device of claim 11 , wherein the first member defines two additional holes.

18. The surgical device of claim 11 , wherein the second member defines at least four holes.

19. The surgical device of claim 11 , wherein the second member holes are for housing suture during the tissue repair.

20. The surgical device of claim 11 , wherein the portion of the second opposing surface opposite the recessed surface portion defines a planar surface that is substantially parallel to the first opposing surface.

21. A surgical device for tissue repair comprising:
a first member having first and second opposing surfaces, the first opposing surface having a non-recessed surface portion and a recessed surface portion, the recessed surface portion having a planar shape, the first member having an inner perimeter extending from the non-recessed surface portion to the recessed surface portion, the recessed surface portion and the inner perimeter defining a recessed portion, the first member defining a hole extending from the recessed surface portion to the second opposing surface, the first member further having an intermediate portion and end portions extending from the intermediate portion, the first member configured to receive a second member within the recessed portion of the first member with the inner perimeter of the first member adjacent to an outer perimeter of the second member such that a combined surface area of a surface of the second member and the non-recessed surface portion of the first opposing surface of the first member is larger than a surface area of the surface of the second member.

22. The surgical device of claim 21 , wherein the first member hole comprises an elongated hole.

23. The surgical device of claim 21 , wherein the first member hole is configured to be axially aligned with a hole in the second member when the second member is received within the recessed portion.

24. The surgical device of claim 21 , wherein the recessed portion is configured to provide a snap-fit with the second member.

25. The surgical device of claim 21 , wherein the recessed portion is configured to provide an interference-fit with the second member.

26. The surgical device of claim 21 , further comprising a suture extending through the first member hole.

27. The surgical device of claim 21 , wherein the first member defines two additional holes.

28. The surgical device of claim 21 , wherein a surface portion of the intermediate portion on the second opposing surface is substantially parallel to surface portions of the end portions on the second opposing surface.
