Abstract

A method of attaching target tissue to a pilot hole in a bone that utilizes a suture assembly having an anchor sleeve; a sliding suture, having a first end and a second end, and passing through the anchor sleeve; and a shuttle having a shuttle loop and a free end, opposed to the shuttle loop, and passing through the anchor sleeve, with the free end and the shuttle outside of the anchor sleeve. In the method, the sliding suture is passed about the target tissue and the first end is engaged to the shuttle loop. Then, the anchor sleeve is pushed into the pilot hole, and the free end is pulled to pull the shuttle into the anchor sleeve in the pilot hole, thereby setting the anchor sleeve into the pilot hole.

First claim

What is claimed is:

1. A method of connecting two pieces of tissue, comprising:
a. providing a repair assembly, including:
i. a repair piece, having a finger trap sleeve, a repair loop in fixed relationship to said sleeve and attached to a first end of said sleeve, and a repair strand extending out of a second side of said sleeve, opposed to said first end of said sleeve, said repair strand terminating in a repair strand free end;
ii. a shuttle, including a shuttle loop and a shuttle strand that extends from said shuttle loop and passes through said sleeve, and terminating in a shuttle strand free end; and

b. passing said shuttle loop and said repair strand free end through both of said two pieces of tissue, so that said repair loop and shuttle strand free end are separated from said shuttle loop and repair strand free end by said two pieces of tissue;
c. threading said repair strand free end through said repair loop and said shuttle loop, consecutively;
d. pulling on said shuttle strand free end, and thereby pulling said repair loop through a said piece of tissue;
e. pulling said shuttle entirely free of said repair piece, and leaving said repair piece, looping through and about said two pieces of tissue, with said finger trap sleeve adjacent to said two pieces of tissue and said a portion of said repair strand trapped in said finger trap sleeve.

2. The method of claim 1 , wherein said shuttle loop is made of comprises nitinol.

3. The method of claim 2 , wherein at least a portion of the said shuttle loop comprises a roughened surface.

4. The method of claim 1 , wherein said two pieces of tissue comprises at least a portion of the meniscus of the knee joint and have been mutually separated by a tear.

5. The method of claim 1 , wherein said two pieces of tissue comprise at least a portion of a glenoid and at least a portion of a labrum.

6. The method of claim 1 , wherein said step of pulling said shuttle entirely free of said repair piece induces said two pieces of tissue to move toward each other.

7. The method of claim 1 , wherein said step of pulling said shuttle entirely free of said repair piece engages said two pieces of tissue together.

8. The method of claim 1 , wherein said repair piece further comprises an implantable tail and said shuttle loop further comprises a shuttle tail.

9. The method of claim 8 , wherein said implantable tail or said shuttle tail comprises a suture material.

10. The method of claim 8 , wherein said implantable tail and said shuttle tail comprise a suture material.
