  • Patent number: 9192370
    Abstract: A suture anchor is provided including an elongate shank defining a longitudinal axis and having at least one bone-engaging thread formed thereon, and a drive head having a proximal end and a distal end mated to the elongate shank. The drive head has a substantially oval shape and includes at least one suture attachment member formed in a portion of the drive head. The configuration of the drive head is particularly advantages in that it provides a suture anchor having improved physical properties, including a high failure torque and a high stripping strength.

  • Patent number: 8956410
    Abstract: A radially expandable sheath is provided having a substantially closed distal end with at least two sidewalls extending proximally therefrom and defining a central lumen. Each sidewall can have a substantially concave outer surface adapted to seat a graft member, and each side wall is at least partially separated by a longitudinally oriented slot that extends from a proximal end along a substantial length of each sidewall. The slot preferably terminates at a position just proximal to the distal end. The device can also include a sheath expander that is adapted to be disposed in the central lumen of the radially expandable sheath and that is configured to flex the sidewalls to radially expand the sheath so as to fix a graft member within a bone tunnel.

  • Publication number: 20150018881
    Abstract: Devices and methods for anchoring tissue to bone are provided. In one embodiment, a suture anchor is provided that includes a bone screw and a collar that can be configured to rotate independent of the bone screw. In one aspect, the collar can be rotatably disposed on a cylindrical seating portion of the bone screw. The collar can include an eyelet and a hook that is angularly offset from the eyelet. In use, a suture loop can be fixedly attached to the collar through the eyelet.
