20110054259 | MINIMALLY INVASIVE RETRACTOR AND METHODS OF USE - 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. | 03-03-2011 |
20120022598 | SPINAL FIXATION SYSTEM - A method for immobilizing a spine. The method includes the steps of implanting at least one low profile screw assembly into a first portion of the spine, implanting at least one bone screw assembly that is not a low profile screw into a second portion of the spine and connecting a rod to both the at least one low profile screw assembly to the at least one bone screw assembly which is not a low profile screw. | 01-26-2012 |
