  • Minimally invasive retractor and methods of use
    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.

  • Minimal incision maximal access MIS spine instrumentation and method
    Patent number: 9095301
    Abstract: A minimal incision maximal access system allows for maximum desirable work space exposure within the incision along with maximum access to the operative field utilizing a minimum incision as small as the width of the working tube. Instead of multiple insertions of dilating tubes the design is a streamlined single entry device to avoid repetitive skin surface entry. The system offers the capability to expand to optimum exposure size for the surgery utilizing retractors depending from a bi-hinged frame having internal or external controls to control the angle and separation of the retractors. Interchangeable retractor blades can be attached to the frame. Both retractor blades are independently controlled as to displacement and angle.
