Abstract

Devices, systems and/or methods for repairing soft tissue adjacent a repair site. In one embodiment, a repair device includes a plate member and an anchor. The plate member having a periphery, the plate member configured to be positioned along an outer surface of the soft tissue. The anchor includes a base and six legs extending from the base, the six legs extending from the base being moveable to a curled configuration such that the six legs wrap around separate portions of the periphery of the plate member with the soft tissue therebetween. In this manner, the repair device may be anchored to the soft tissue.

3. The soft tissue repair device of claim 1, further comprising one or more filaments configured to be coupled to the first plate or the first anchor.

4. The soft tissue repair device of claim 1, wherein one of the at least two tapers extend at an angle between about 1 degree and 10 degrees.

5. The soft tissue repair device of claim 1, wherein the base of the first anchor is configured to be positioned over the soft tissue with the at least four legs extending into the soft tissue such that the base is positioned along the outer surface of the soft tissue at an opposite side of the first plate.

6. The soft tissue repair device of claim 1, wherein the at least four legs of the first anchor comprises at least six legs.

7. The soft tissue repair device of claim 1, wherein the first plate comprises tines extending therefrom, the tines configured to extend into the soft tissue.

8. The soft tissue repair device of claim 1, wherein the peripheral edge of the first plate extends with curved portions each sized and configured to receive one of the at least four legs of the first anchor to curl therearound.

9. The soft tissue repair device of claim 8, wherein at least one of the curved portions defined along the peripheral edge at least partially defines an aperture defined in the first plate.

10. The soft tissue repair device of claim 1, wherein the first anchor is a monolithic structure, and wherein the second anchor is a monolithic structure.

11. The soft tissue repair device of claim 1, wherein the first plate is coupled to the second plate with one or more filaments.

12. The soft tissue repair device of claim 1, wherein the first anchor is coupled to the second anchor with one or more filaments.

18. The soft tissue repair device of claim 11, wherein the first plate and the second plate each comprise tines extending therefrom, the tines configured to extend into the soft tissue.

13. A soft tissue repair device for repairing soft tissue at a soft tissue repair site, comprising:

a first plate having a first peripheral edge defining a first plate thickness, the first plate configured to be positioned along an outer surface of the soft tissue;

a second plate coupled to the first plate, the second plate having a second peripheral edge defining a second plate thickness, the second plate configured be positioned along the outer surface of the soft tissue such that the second plate is longitudinally aligned with the first plate;

a first anchor having a base and at least four legs extending from the base, the first anchor movable from a first position to a second position, the second position exhibiting a curled configuration; and
