Abstract

The present disclosure relates to a two-piece implant. The implant includes a first piece having at least two prongs and a protrusion located between the prongs and a second piece coupled to the first piece, wherein the second piece is configured to rotate relative to the first piece. A method of tissue repair is also disclosed.

First claim

What is claimed is:

1. A method of tissue repair comprising:
preparing a hole in a bone;
placing a soft tissue over the hole;
inserting a two-piece implant into the hole in the bone such that the implant advances the soft tissue into the hole in the bone, the two-piece implant including a first piece and a second piece coupled to the first piece, the first piece having at least two prongs, a protrusion located between the prongs, and a snap-fit feature, each prong extending substantially parallel to a longitudinal axis of the implant to a prong free end, the protrusion extending substantially parallel to the longitudinal axis of the implant to a protrusion free end, the second piece including a bottom surface having an opening configured for engagement with the snap-fit feature and a top surface including a hole configured for engagement with a delivery device, the opening and the hole separated from one another along the longitudinal axis of the implant via a material separation, the material separation serving as a top surface of the opening and a bottom surface of the hole, the soft tissue located between the prongs upon insertion.

2. The method of claim 1 wherein the soft tissue is advanced into the hole in the bone such that the protrusion of the first piece engages the soft tissue and the second piece is rotated relative to the first piece to advance the implant and the soft tissue into the hole in the bone.

3. The implant of claim 2 wherein each of the at least two prongs include at least one radially-extending barb, the barb engaging the bone when the implant is advanced into the hole in the bone.

4. The implant of claim 2 wherein the second piece includes threads on an outer surface of the second piece, the threads allowing for rotation of the second piece and advancement of the implant into the hole in the bone.

5. The method of claim 1 wherein the implant includes a transverse opening located between the protrusion and a top surface of the first piece.

6. The method of claim 5 wherein at least one flexible member is disposed within the transverse opening.

7. The method of claim 6 further comprising placing ends of the at least one flexible member around the soft tissue before inserting the implant into the hole in the bone.

8. The method of claim 6 wherein the at least one flexible member is used to couple the implant to the delivery device.
