  • Patent number: 10219844
    Abstract: A spine fixation device including an elongated bone screw partially embedded in a vertebra of a spine and a retaining head that can receive a rod and a head of the bone screw. The retaining head has an inner member that includes a screw head receiving section for receiving the screw head. The retaining head further has an outer member that includes an inner face that can contact an outer face of the screw head receiving section. When the inner face is in contact with the outer face, the screw head receiving section applies pressure to the screw head to fixate the relative angle between the bone screw and the retaining head.

  • Patent number: 10194896
    Abstract: A retractor system is provided having a plurality of blade portions that collectively present a low profile tapered configuration for insertion through tissue along a natural tissue plane. Once inserted through tissue the blade portions may be independently moved apart to form an access path to a surgical site, such as by first moving the blade portions apart along the natural tissue plane followed by moving the blade portions apart transverse to the natural tissue plane. The blade portions may be attached to retractor frame members, and rack and pinion frame components may be used to control movement of the blade portions relative to one another. Pins may be used to secure the blade portions to bone.

  • Patent number: 10149771
    Abstract: A B-shaped implant for insertion into a disc space between adjacent vertebral bodies. The implant includes first and second projecting lobes configured to sit on bony prominences adjacent a posterior rim of a lower one of the vertebral bodies. A concave recess between the two projecting lobes is configured to avoid impact with the vertebral foramen. An anterior portion wall connects ends of the B-shaped implant, cooperating with the projecting lobes to define fill spaces. The fill spaces can be packed with bone growth material. The implant can be expandable, made of rotatable interconnected links, which can be inserted into the disc space in an unexpanded position, and expanded in the disc space to an expanded position.

  • Patent number: 10080591
    Abstract: A resilient core is positioned between bony projections which are offset from a principal load bearing region of a spinal joint. Shaped projections extend from the core, and engage the bony projections by conforming to anatomical landmarks, and may be fastened to the bony projections. During flexion of the joint, the core absorbs some of the force of compression, and limits an extent to which the joint may compress. If the shaped projections are connected to the bony projections, extension of the joint is inhibited by the projections and the core, limiting the extent to which the joint may be distracted. In this manner, healing is fostered, and a weakened or damaged joint is protected from excessive movement.
