  • Patent number: 11950787
    Abstract: Cutting instruments and related methods are disclosed herein in which the diameter of the retrograde cutting blade can be adjusted to any of a plurality of diameter settings, allowing the same instrument to be used to form holes of different diameters. The limit diameter can be preset such that, during the cutting operation, the user need not be concerned with selecting the appropriate diameter, but rather can simply deploy the cutting blade until the preset limit is reached. Cutting instruments are also disclosed in which the retrograde cutting blade is distinct from the forward drilling tip and protected within a cavity formed in the body of the instrument when not in use, as are instruments in which the user is given visual and/or tactile feedback to confirm desired positioning of the cutting blade.

  • Patent number: 10667803
    Abstract: Devices and methods for anchoring tissue to bone are provided herein. In various embodiments, the tissue anchor systems and methods can provide a length of suture having terminal ends coupled to one another via a sliding knot so as to define a suture loop having an adjustable length. After passing a portion of the suture loop through a damaged tissue and coupling the suture loop to bone, the sliding knot can be advanced to shorten the suture loop in order to secure the tissue to bone.

  • Patent number: 10617407
    Abstract: A suture anchor is disclosed having an outer body with an axial bore which receives and inner body for rotation. Suture passes between the inner body and outer body and rotation of the inner body wraps the suture thereabout locking the suture thereto. Rotation of the inner body also effects radial expansion of at least a portion of the outer body to engage to anchor into a bone hole.

  • Publication number: 20200078163
    Abstract: Various methods and devices are provided for a graft fixation device for fixing a graft member within a bone tunnel. In one embodiment, a graft fixation device is provided having a radially expandable sheath adapted to be disposed within a bone tunnel, and a sheath expander adapted to be received within the radially expandable sheath to expand the sheath and thereby anchor a graft between the sheath and the bone tunnel. In an exemplary embodiment, the graft fixation device is particularly useful to affix a graft within a femoral tunnel.

  • Patent number: 10512475
    Abstract: Methods and devices are provided for implanting a cross-pin through a bone tunnel, such as in an arthroscopic surgical procedure. In general, the methods and devices allow a cross-pin hole to be formed in a medial side of a knee bone such that it intersects a bone tunnel formed in the knee bone. In one embodiment, a cross-pinning guide device is provided that can be configured to angularly position the cross-pin hole relative to the bone tunnel to allow the cross-pin hole to intersect the bone tunnel without passing through another side, e.g., a lateral side, of the knee bone. The knee bone can be a femur or a tibia such that the cross-pin hole and the bone tunnel can each be entirely formed in the femur or in the tibia.

  • Patent number: 10045771
    Abstract: A suture anchor comprises a shell and an anchor member. The shell comprises a body having a distal end, a proximal end and sidewalls therebetween defining an axial cannulation therethrough. The anchor member comprises a body having a distal end and a proximal end which is sized to fit within the cannulation. The sidewalls define a lateral cut-out such that with the anchor member received within the cannulation a first lateral portion of the anchor member is exposed laterally and a second, laterally opposite, lateral portion of the anchor member is enclosed by the sidewalls. A friction enhancement on the first lateral portion frictionally engages a bone surface when the suture anchor is disposed within a bone tunnel defined by the bone surface. Suture is trapped between the shell and the anchor and also between the anchor and the bone surface.

  • Patent number: 9814508
    Abstract: Devices and methods are provided for positioning and forming bone tunnels. In one embodiment, a surgical drill guide apparatus is provided. The apparatus can include a first guide member having a longitudinal passageway extending therethrough for aiming a first guide pin along a first path to form a first bone tunnel. The apparatus can also include a second guide member having a longitudinal passageway extending therethrough for aiming a second guide pin along a second path to form a second bone tunnel. The first and second guide members can extend at an angle relative to one another and they can be offset such that axes of the guide members do not intersect.
