20100087925 | SPINAL INTERBODY SPACER - A spinal spacer for engagement between vertebrae includes a body extending between a substantially contoured first end surface and a second end surface to define side surfaces and opposing top and bottom vertebral engaging surfaces substantially symmetrical about a centerline axis. At least one opening defines a hollow inner body and includes first and second intersecting openings extending through the top and bottom vertebral engaging surfaces. The second intersecting opening extends through the side surfaces. The second end surface includes at least one aperture formed therethrough in communication with the hollow inner body. A screw opening is defined through at least one plate insert configured to be removably coupled to the second end surface to substantially align the screw opening with the at least one aperture. The bone screw is configured to be threadingly secured within the at least one plate insert. | 04-08-2010 |
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 |

20140213853 | MINIMALLY OPEN RETRACTION DEVICE - A retractor having a pair of blades is disclosed. A ring having an opening is attached to one end of the blades. The blades define a channel therebetween. The blades may be pivotally coupled to the ring. The retractor may have at least two conditions. In a first condition, the retractor is insertable through an incision in a patient's skin to an operative site. In a second condition, the retractor may be manipulated for retracting tissue surrounding the operative site. Instruments, prostheses, or tissue may be inserted or removed through the channel of the retractor. | 07-31-2014 |
