  • Patent number: 10478200
    Abstract: The present disclosure relates to a system and method for repairing an articular surface. A guide pin may be secured to an articular surface of a glenoid, wherein the guide pin defines a working axis and the working axis is positioned at an angle ? relative to the articular surface, wherein angle ? is less than or equal to 90 degrees. An excision device may be advanced over the guide pin, wherein the excision device includes a cannulated shaft and at least one cutter, wherein the at least one cutter is generally aligned in a single plane. A generally hemi-spherical excision site may be formed with the excision device within the articular surface of the glenoid.

  • Patent number: 10433833
    Abstract: An apparatus includes first and second fixation members, a flexible member coupled to the first and second fixation members, and a limiting element coupled to the flexible member. The limiting element is movable relative to the second fixation member and acts to limit loosening of the flexible member relative to the second fixation member. The limiting element can be slidably received by the flexible member. The flexible member can be coupled to the fixation members such that pulling on a free end of the flexible member shortens a length of the flexible member between the fixation members.
