  • Patent number: 9161779
    Abstract: A device, system and method for orthopedic spine surgery using a novel screw-based retractor, disclosed herein, that allows for access to the spine through a minimally or less invasive approach. The retractor device is designed to be coupled to a pedicle screw and then to have opposed arms of the retractor spread apart to open the wound proximally. The retractor is removed by pulling it out of the wound whereby the retractor is deformed to pass over the pedicle screw head. The retractor is intended to be made of a stiff plastic material, sterile packaged and disposable after one use. A system and method for using the retractor and performing a minimally invasive spine surgical procedure are also disclosed.

  • Patent number: 9107707
    Abstract: A spinal stabilization system may include a pair of structural members coupled to at least a portion of a human vertebra with connectors. Connectors may couple structural members to spinous processes. Some embodiments of a spinal stabilization system may include fasteners that couple structural members to vertebrae. In some embodiments, a spinal stabilization system, provides three points of fixation for a single vertebral level. A fastener may fixate a facet joint between adjacent vertebrae and couple a stabilization structural member to a vertebra. Connectors may couple the structural members to the spinous processes of the vertebrae. Use of a spinal stabilization system may improve the stability of a weakened or damaged portion of a spine. When used in conjunction with an implant or other device, the spinal stabilization system may immobilize vertebrae and allow for fusion of the implant or other device with vertebrae.

  • Patent number: 9101400
    Abstract: A flexible connection unit for use in a spinal fixation device is provided. The flexible connection unit includes an elongated member, such as a vertebral rod, having a first end portion and a second end portion opposite each other with a transition portion extending therebetween. The first end portion of the vertebral rod comprises an oval shape and the second end portion contains an oval or non-oval shape. The major diameter of the oval shaped first end is parallel to the sagittal plane of a patient's body and provides the higher stiffness for fusion to resist flexion in the sagittal plane. The second end portion of the vertebral rod is perpendicular to the sagittal end of a patient's body and provides the lower stiffness for fusion.
