Expanding knotless suture anchor

A suture anchoring device, comprising:

• a radially expandable implant body defining a body bore space extending longitudinally about a central axis from a proximal end to a distal end of the implant body;
• at least one relief slot defined in the implant body, each at least one relief slot extending from the distal end of the implant body, and each at least one relief slot configured to allow the distal end of the implant body to radially expand relative to the proximal end of the implant body;
• an interference portion provided on an interior surface of the distal end of the implant body and extending into the body bore space;
• an anchor having a head portion and an extension portion extending therefrom such that the extension portion does not move relative to the head portion, the extension portion defining an extension bore space therein, the extension portion configured to be received in the body bore space such that the distal end of the implant body abuts the head portion of the anchor and the extension portion is prevented from extending through the at least one relief slot;
• a slot defined by the extension portion, the slot configured to receive the interference portion of the implant body;
• and
• a plug configured to be received in the extension bore space;
• wherein the head portion of the anchor defines the distalmost end of the suture anchoring device.
