Abstract

A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone. The method includes the following: implanting in bone a first anchor including a first suture construct connected to the first anchor; passing a first adjustable loop of the first suture construct at least one of over or through the soft tissue; coupling the first adjustable loop to one of a first locking feature of the first anchor or a second locking feature of a second anchor; adjusting the first adjustable loop by pulling a first end of the first suture construct; and securing the soft tissue against bone by pulling the first end of the first suture construct.

First claim

What is claimed is:

1. A method for coupling soft tissue to bone, comprising:
driving a first anchor into a bone while a first adjustable suture construct that is coupled to the first anchor extends away from the first anchor, the first adjustable suture construct including a first free end that passes through a first longitudinal passage in the first adjustable suture construct to form a first adjustable loop and a second free end that passes through a second longitudinal passage in the first adjustable suture construct to form a second adjustable loop, the first longitudinal passage spaced apart from the second longitudinal passage in the first adjustable suture construct;
passing the first adjustable loop of the first adjustable suture construct at least one of over or through the soft tissue;
coupling the first adjustable loop to one of a first locking feature of the first anchor or a second locking feature of a second anchor after said driving of the first anchor into the bone; and
pulling on the first free end of the first adjustable suture construct to reduce a size of the first adjustable loop for securing the soft tissue against the bone.

2. The method of claim 1 , wherein the first adjustable loop is coupled to a hook of one of the first locking feature or the second locking feature.

3. The method of claim 1 further comprising driving the second anchor into the bone, wherein the first adjustable loop is coupled to the second locking feature of the second anchor prior to driving the second anchor into the bone.

4. The method of claim 3 , wherein the second anchor is driven into the bone before said pulling on the first free end of the first adjustable suture construct.

5. The method of claim 1 , wherein the first adjustable loop is coupled to a first locking feature of the first anchor after said driving of the first anchor into the bone.

6. The method of claim 1 , further comprising:
passing the second adjustable loop of the first adjustable suture construct at least one of over or through the soft tissue;
coupling the second adjustable loop to a third locking feature of a third anchor; and
pulling on the second free end of the first adjustable suture construct to reduce a size of the second adjustable loop for securing the soft tissue against the bone.

7. The method of claim 1 , further comprising:
implanting the second anchor in bone;
passing a third adjustable loop of a second adjustable suture construct connected to the second anchor at least one of over or through the soft tissue;
coupling the third adjustable loop to a third locking feature of a fourth anchor; and
pulling on a third free end of the second adjustable suture construct to reduce a size of the third adjustable loop for securing the soft tissue against the bone.

8. A method for coupling soft tissue to bone, comprising:
driving a first anchor into a bone while a first adjustable suture construct that is coupled to the first anchor extends away from the first anchor, the first adjustable suture construct including a first free end that passes through a first longitudinal passage in the first adjustable suture construct to form a first adjustable loop and a second free end that passes through a second longitudinal passage in the first adjustable suture construct to form a second adjustable loop, the first longitudinal passage spaced apart from the second longitudinal passage in the first adjustable suture construct;
passing the first adjustable loop of the first adjustable suture construct at least one of over or through the soft tissue;
coupling the first adjustable loop to a first locking feature of a second anchor after said driving of the first anchor into the bone; and
pulling on the first free end of the first adjustable suture construct to reduce a size of the first adjustable loop for securing the soft tissue against the bone.

9. The method of claim 8 , further comprising driving the second anchor into the bone before said pulling on the first free end of the first adjustable suture construct.

10. The method of claim 8 further comprising driving the second anchor into the bone, wherein the first adjustable loop is coupled to the first locking feature of the second anchor prior to driving the second anchor into the bone.

11. The method of claim 8 , wherein a second adjustable suture construct is coupled to the second anchor, the second adjustable suture construct substantially the same as the first adjustable suture construct.

12. A method for coupling soft tissue to bone, comprising:
driving a first anchor into a bone while a first suture construct that is coupled to the first anchor extends away from the first anchor;
passing a first adjustable loop of the first suture construct at least one of over or through the soft tissue;
driving a second anchor into the bone;
coupling the first adjustable loop to a first locking feature of the first anchor after said driving of the first anchor into the bone; and
pulling on a first free end of the first suture construct to reduce a size of the first adjustable loop for securing the soft tissue against the bone
wherein the first free end passes through a first longitudinal passage in the first suture construct to form the first adjustable loop, and
wherein the first suture construct includes a second free end that passes through a second longitudinal passage in the first suture construct to form a second adjustable loop, the first longitudinal passage separate from the second longitudinal passage in the first suture construct.

13. The method of claim 12 , wherein the first adjustable loop is coupled to a hook forming the first locking feature of the first anchor.
