Abstract

Devices, systems, and methods to improve both the reliability of soft tissue repair procedures and the speed at which the procedures are completed are provided. The devices and systems include one or more tissue augmentation constructs, which include constructs that are configured to increase a footprint across which suture applied force to tissue when the suture is tied down onto the tissue. The tissue augmentation constructs can be quickly and easily associated with the repair suture, and can be useful in many different tissue repair procedures that are disclosed in the application. In one exemplary embodiment, one or more constructs are disposed on a suture threader, which can be used to associate the construct(s) with a repair suture(s) being used to repair the soft tissue. Tissue augmentation constructs can include various blocks and patches, among other formations. Exemplary methods for manufacturing the tissue augmentation constructs are also provided.

First claim

What is claimed is:

1. A method of soft tissue repair, comprising:
passing a first suture limb through soft tissue;
passing a second suture limb through soft tissue;
attaching a scaffold to each of the first and second suture limbs, wherein such attachment occurs for at least one of the first and second suture limbs by coupling at least one of the first and second suture limbs to a threader pre-disposed through a substantial portion of a longitudinal length of material of the scaffold and applying a force to the threader to advance the threader and the at least one of the first and second suture limbs through the substantial portion of the longitudinal length of material of the scaffold to dispose the scaffold onto the at least one of the first and second suture limbs, thereby increasing a surface area for engaging tissue associated with the at least one of the first and second suture limbs;
advancing a first end of the scaffold to a location that is proximate to locations through which the first and second suture limbs pass through the soft tissue; and
coupling one or more suture tails with at least one suture anchor disposed in the bone to which the soft tissue is being attached.

2. The method of claim 1 , wherein advancing a first end of the scaffold to a location that is proximate to locations through which the first and second suture pass through the soft tissue further comprises disposing a second, opposite end of the scaffold beyond the soft tissue such that it extends over bone to which the soft tissue is being attached.

3. The method of claim 1 , wherein the one or more suture tails are part of one suture from which the first and second suture limbs are formed.

4. The method of claim 1 , wherein the one or more suture tails are separate sutures from sutures that form the first and second suture limbs.

5. The method of claim 1 , wherein attaching a scaffold to each of the first and second suture limbs further comprises:
threading the first suture limb from the first end of the scaffold to the second, opposite end of the scaffold at a location that is more proximate to a first side of the scaffold than a second, opposite side of the scaffold; and
threading the second suture limb from the first end of the scaffold to the second, opposite end of the scaffold at a location that is more proximate to the second, opposite side of the scaffold than the first side of the scaffold,
wherein coupling one or more suture tails with at least one suture anchor disposed in the bone to which the tissue is being attached further comprises coupling a first tail of the one or more suture tails with a first suture anchor disposed in the bone to which the soft tissue is being attached and coupling a second tail of the one or more suture tails with a second suture anchor disposed in the bone to which the soft tissue is being attached.

6. The method of claim 5 , wherein the first suture limb is of a first suture and the second suture limb is of a second suture.

7. The method of claim 6 ,
wherein attaching a scaffold to each of the first and second suture limbs by coupling at least one of the first and second suture limbs to a threader pre-disposed through a substantial portion of a longitudinal length of material of the scaffold and applying force to the threader to advance the threader and the at least one of the first and second suture limbs through the substantial portion of the longitudinal length of material of the scaffold further comprises:
coupling the first suture limb to the threader and applying the force to the threader to advance the threader and the first limb through the substantial portion of the longitudinal length of material of the scaffold to dispose the scaffold onto the first suture limb; and
coupling the second suture limb to a second threader pre-disposed through a substantial portion of a longitudinal length of material of the scaffold and applying a force to the second threader to advance the second threader and the second limb through the substantial portion of the longitudinal length of material of the scaffold to dispose the scaffold onto the second suture limb.

8. The method of claim 6 , further comprising:
installing a first medial row stitch using the first suture; and
installing a second medial row stitch using the second suture,
wherein coupling one or more suture tails with at least one suture anchor disposed in the bone to which the soft tissue is being attached further comprises installing a lateral row fixation.

9. The method of claim 6 , wherein the first suture includes a third suture limb and the second suture includes a fourth suture limb, the method further comprising:
passing the third suture limb over the scaffold and coupling it to the second suture anchor; and
passing the fourth suture limb over the scaffold and coupling it to the first suture anchor, thereby forming a crossed configuration with the third and fourth suture limbs.

10. The method of claim 9 , further comprising:
installing a first medial anchor to which the first suture is coupled such that the first and third suture limbs extend from the first medial anchor; and
installing a second medial anchor to which the second suture is coupled such that the second and fourth suture limbs extend from the second medial anchor.

11. The method of claim 6 , wherein the first suture includes a third suture limb and the second suture includes a fourth suture limb, the method further comprising:
threading the third suture limb from the first end of the scaffold to the second, opposite end of the scaffold and coupling the third suture limb to the second suture anchor; and
threading the fourth suture limb from the first end of the scaffold to the second, opposite end of the scaffold and coupling the fourth suture limb to the first suture anchor, thereby forming a crossed configuration with the third and fourth suture limbs.

12. The method of claim 11 , further comprising:
installing a first medial anchor to which the first suture is coupled such that the first and third suture limbs extend from the first medial anchor; and
installing a second medial anchor to which the second suture is coupled such that the second and fourth suture limbs extend from the second medial anchor.

13. The method of claim 11 ,
wherein attaching a scaffold to each of the first and second suture limbs by coupling at least one of the first and second suture limbs to a threader pre-disposed through a substantial portion of a longitudinal length of material of the scaffold and applying force to the threader to advance the threader and the at least one of the first and second suture limbs through the substantial portion of the longitudinal length of material of the scaffold further comprises:
coupling the first suture limb to the threader and applying the force to the threader to advance the threader and the first limb through the substantial portion of the longitudinal length of material of the scaffold to dispose the scaffold onto the first suture limb;
coupling the second suture limb to a second threader pre-disposed through a substantial portion of a longitudinal length of material of the scaffold and applying a force to the second threader to advance the second threader and the second limb through the substantial portion of the longitudinal length of material of the scaffold to dispose the scaffold onto the second suture limb;
coupling the third suture limb to a third threader pre-disposed through a substantial portion of a longitudinal length of material of the scaffold and applying a force to the third threader to advance the third threader and the third limb through the substa
