Abstract: A knotless interference or contact fixation anchor assembly comprising an anchor body with a removable inserter/driver that fully supports the suture anchor over its entire working length. The anchor body may also incorporating a suture trap that is housed within a proximal eyelet of the anchor body. The anchor body may include a plurality of elongate ribs extending longitudinally along at least a portion of the anchor body. The plurality of ribs comprise flexible barbs. When inserted into bone or a bone tunnel, the barbs compress slightly, resulting in less bone compression around the anchor due to the forces required for insertion, and increased pull-out resistance.

Abstract: Embodiments of the invention include devices and methods for providing an anchor in tissue. An anchor of some embodiments is formed from strands of material combined together into a body and one or more elongated members extending from a distal end of the body that include one or more of the strands of material from which the proximal end of the body is formed. The elongated members may be pulled back through the body and pulled proximally relative to the body to laterally expand the body. Some embodiments may also use an inserter with a rod sized to fit in a cannula through the body of the anchor and a tube configured to provide a more rigid structure about the exterior of the anchor during insertion.
