Abstract

A soft tissue repair assembly. The assembly includes a flexible member having first and second ends, and a strand passing through the flexible member. The strand has first and second strand ends extending through the flexible member, such that pulling at least one of the first and second strand ends changes the flexible member from a first shape suitable for insertion through soft tissue to a second shape suitable for securely lodging the soft tissue repair assembly relative to soft tissue.

Claims

1. A soft tissue repair device, comprising:

a flexible strand having a first end and a second end and coupled to the first deformable anchor and the first deformable vascularization conduit, wherein upon pulling on at least one end of the flexible strand causes the first deformable anchor to deform from the first shape to the second shape; and

a first strand loop passing at least partially through a longitudinal bore of the first deformable anchor and having first and second loop ends extending outside the bore of the first deformable anchor.

2. The device of claim 1, wherein the flexible strand passes through the first and second loop ends of the first strand loop.

3. The device of claim 2, wherein the flexible strand extends through at least a portion of an inner bore of the first deformable vascularization conduit.

4. The device of claim 3, further comprising a second deformable anchor, the second deformable anchor deformable from a third shape to a fourth shape different from the third shape, wherein the flexible strand is coupled to the second deformable anchor.

5. The device of claim 4, further comprising a second deformable vascularization conduit having a side wall and defining a plurality of perforations extending through the side wall, wherein the flexible strand is coupled to the second deformable vascularization conduit.

6. The device of claim 4, wherein the first deformable vascularization conduit extends from a first end to a second end and the first anchor is positioned at the first end and the second anchor is positioned at the second end and the flexible strand extends through the side wall of the first deformable vascularization conduit.

7. A soft tissue repair device comprising:

a first deformable anchor defining an internal longitudinal bore and having first and second ends;

a first strand loop passing at least partially through the longitudinal bore of the first deformable anchor and having first and second loop ends extending outside the bore of the first deformable anchor;

a first tubular conduit for vascularization including an outer surface, a longitudinal inner bore extending between first and second open ends of the first tubular conduit and a plurality of perforations extending from the inner bore through the outer surface of the first tubular conduit; and

a flexible strand having first and second strand ends and coupled to the first and second loop ends of the first strand loop, the flexible strand extending substantially outside the first deformable anchor, the flexible strand passing through the inner bore of the first tubular conduit, such that pulling at least one of the first and second strand ends deforms the first deformable anchor from a first shape suitable for insertion through soft tissue to a second shape suitable for securely lodging the soft tissue repair device relative to the soft tissue.

8. The device of claim 7, wherein the first and second strand ends pass through the second end of the first tubular conduit.

9. The device of claim 7, wherein the first tubular conduit is deformable.

10. The device of claim 7, further comprising:

a second deformable anchor defining an internal longitudinal bore and having first and second ends; and

a second strand loop passing at least partially through the longitudinal bore of the second deformable anchor and having first and second loop ends extending outside the bore of the second deformable anchor; and

wherein the flexible strand passes through the first and second loop ends of the second deformable anchor.

11. The device of claim 10, wherein the first and second ends of the flexible strand pass through an opening between the first and second ends of the tubular conduit.

12. The device of claim 7, further comprising:

a second tubular conduit for vascularization including an outer surface, a longitudinal inner bore extending between first and second open ends of the second tubular conduit and a plurality of perforations extending from the inner bore through the outer surface of the second tubular conduit;

a second deformable anchor defining an internal longitudinal bore and having first and second ends; and

a second strand loop passing at least partially through the longitudinal bore of the second deformable anchor and having first and second loop ends extending outside the bore of the second deformable anchor; and

wherein the flexible strand passes through the first and second loop ends of the second deformable anchor and through the inner bore of the second tubular conduit.

13. The device of claim 12, wherein the first and second deformable anchors comprise woven material.

14. The device of claim 12, wherein the first and second tubular conduits are deformable.

15. The device of claim 14, wherein the first and second tubular conduits comprise woven material.

16. A soft tissue repair device comprising:

a first deformable anchor defining an internal longitudinal bore and having first and second ends;

a first strand loop passing at least partially through the longitudinal bore of the first deformable anchor and having first and second loop ends extending outside the bore of the first deformable anchor;
