20090018399 | Surgical access system and related methods - A surgical access system including a tissue distraction assembly | 01-15-2009 |
20100106191 | CONICAL INTERSPINOUS APPARATUS AND A METHOD OF PERFORMING INTERSPINOUS DISTRACTION - A conical interspinous apparatus comprising: an insertion portion with a proximal end, a distal end, and conical screw-shaped grooves configured to distract two adjacent spinous processes; a shaft portion, coupled to the distal end of the insertion portion, and having a smaller cross-section than a cross-section at the distal end of the insertion portion, such that the two spinous processes rest on the shaft portion; and a clamp portion being movable and securable along the shaft, and being configured to secure the two spinous processes between the clamp portion and the distal end of the insertion portion. | 04-29-2010 |
20100249644 | System and Methods for Performing Dynamic Pedicle Integrity Assessements - The present invention involves systems and related methods for performing dynamic pedicle integrity assessments involving the use of neurophysiology. | 09-30-2010 |
20120101582 | Implants and Methods for Spinal Fusion - An implant is provided for performing spinal fusion. The implant includes an implant body having a leading side and a trailing side at opposing ends along a longitudinal axis. Between the leading side and trailing side are an upper surface, a lower surface, an anterior side, and a posterior side. At least one keel structure is provided extending from the implant body for penetration into an adjacent vertebral body. A trial sizer and keel cutter may be utilized to form keel channels within the vertebral body to receive the keel structure. | 04-26-2012 |
20120116462 | POLYAXIAL BONE SCREW - A polyaxial bone screw includes a shaft, a body member, and a toroidal member. The shaft includes a longitudinal axis and a proximal end with a head having a generally rounded surface. The body member has a bore disposed longitudinally therethrough and a groove defined by a luminal surface of the bore. The toroidal member has an elliptical cross-section with a major axis and disposed within the groove to engage the generally rounded surface of the head at a point of contact. | 05-10-2012 |
20120184993 | EXPANDABLE FACET SCREW - An exemplary facet screw for joining a first facet of a first vertebra with a second facet of a second vertebra includes proximal and distal ends. The proximal end includes a threaded region for attachment to the first facet. The distal end includes a non-threaded region with a first configuration that freely inserts into a bore of the second facet and a second configuration that partially interferes with the bore to retain the distal end within the second facet. | 07-19-2012 |
20120203287 | MATERIAL DELIVERY APPARATUS FOR A BONE SCREW - A material delivery apparatus for a bone screw includes an attachment member having a lumen disposed therethrough and adapted to removably attach to the bone screw. The apparatus further includes a delivery cannula fixedly disposed through the lumen and adapted to extend into a central bore of the bone screw for the delivery of material thereinto. | 08-09-2012 |
20140180423 | SYSTEM AND METHODS FOR SPINAL FUSION - A spinal fusion system and related methods involve the use of a spinal fusion implant of non-bone construction. The spinal fusion implant is particularly suited for introduction into the disc space via a lateral approach to the spine. | 06-26-2014 |
