Title: TAP-IN BONE ANCHOR WITH EXPANDING RING
Abstract:
An anchoring device for holding suture in bone includes an implant body with a proximal end and a distal end. A distal opening of the implant body is configured to receive a first proximal portion of an anchor. An expandable ring is initially press-fit about the first proximal portion of the anchor. The anchoring device is then located in a pre-drilled bore in a bone portion and the anchor portion is drawn proximally into the implant body, causing the ring to expand and contact the inner walls of the bone bore thus providing additional locking force of the anchoring device in the bone.
