ABSTRACT:
A novel suture anchor comprising (a) a coupling member having a first end portion and a reduced second end portion, and a shoulder formed at the junction of the first end portion and the reduced second end portion, (b) at least one barb, the barb having a first end and a second end and being curved in its normal unstressed state and being capable of being elastically deformed to a substantially straight configuration, the barb being attached to the coupling member so that the second end of the barb is substantially displaced from the coupling member when the barb is in its normal unstressed state but is capable of being aligned with the coupling member when the barb is deformed to a substantially straight length, and (c) attachment means for attaching one end of a suture to the suture anchor. The suture anchor is installed in a hole in bone using a suitable installation tool by aligning the second end of the barb with the coupling member, inserting the anchor in the hole, and then permitting the second end of the barb to assume a displaced position whereby the barb and coupling member are driven into engagement with the sidewall of the hole.
