20110077655 | Vertebral Body Spool Device - A mandrel is inserted into the tissue to be distracted and a filament is repeatedly wrapped around the mandrel to make a spool. As the mandrel turns, the filament coils around the mandrel to create of spool of increasing diameter. This spool can be used as a distractor, tamp, or implant. A spool implant can be cemented to further stabilize the device in situ, such as a vertebral body. The filament deposition upon the mandrel is controlled by rotation and the volume creation is incremental. This makes the spool ideal for creating highly controlled distraction forces or insertion of bulking material. In some embodiments, fibers having a low glass transition temperature are used. | 03-31-2011 |
20110097377 | Methods and Devices for Correcting Spinal Deformity With Pharmaceutical-Eluting Pedicle Screws - A method of correcting spinal deformity, which includes locating pharmaceutical-loaded implants adjacent to targeted spinal growth plates, and then eluting the pharmaceutical onto the growth plates. Preferably, the method involves correcting spinal deformity by simply inserting a pharmaceutical-eluting pedicle screw onto the concave side of a scoliotic curve. In some embodiments, the screw has a cannulated internal reservoir that contains a growth-inhibiting pharmaceutical (such as a tetracycline) and at least one fenestration that allows the pharmaceutical to elute onto the vertebral body growth plate. | 04-28-2011 |
20110152627 | Neural Tissue Retraction and Preservation Device - A self-retaining neural retraction clip, preferably having controlled retraction level and an off-set retraction means. This device can reduce operative site clutter to enhance disc access while providing consistent and stable dural retraction. | 06-23-2011 |
20110313281 | Instrument for Image Guided Applications - A trackable medical instrument for use in a computer assisted image guided surgery system having a digitizer for tracking the position of the instrument in three dimensional space and a display providing an indication of the position of the instrument with respect to images of a body part taken preoperatively, wherein the instrument comprises a tracking array located distally of a rotatable, axially fixed drive handle. | 12-22-2011 |
20110319898 | Instruments and Methods for Non-Parallel Disc Space Preparation - Flexible shavers and curved access ports that reduce access and trajectory problems associated with conventional lateral approaches to the lower spine. These devices and methods allow for preparing a disc space in the lower spine at an angle that is parallel to the disc space. Consequently, these devices and methods allow for preparing with less endplate damage. | 12-29-2011 |
20110319899 | Flexible Vertebral Body Shavers - Several devices and methods for preparing the vertebral endplates while minimizing damage to the vertebral endplates. Each design incorporates flexible means to reduce endplate damage while enabling removal of the cartilage adhered to the endplate cortical bone. | 12-29-2011 |
20110319995 | Enhanced Cage Insertion Device - A method of delivering a fusion cage to an intervertebral disc space bounded by adjacent vertebral endplates, comprising the step of delivering the fusion cage into the disc space without contacting its teeth to the vertebral endplates during delivery, wherein a sheath is interposed between a cage surface and the endplates to prevent contact therebetween during delivery. | 12-29-2011 |
20110319998 | Universal Trial for Lateral Cages - A method of trialing an intervertebral disc space, comprising the steps of:

20110319999 | Lateral Spondylolisthesis Reduction Cage - An intervertebral fusion device comprising inferior and superior fusion cage devices that provide an ability to correct spondylolisthesis via in-situ adjustment. | 12-29-2011 |
20110320000 | Multi-Segment Lateral Cage Adapted to Flex Substantially in the Coronal Plane - The present invention concerns several fusion devices and methods for laterally inserting a fusion device at an initial trajectory that is not parallel to the disc space. Each fusion device incorporates components that enable flexing, bending or pivoting of the device during its final approach to the prepared disc space. | 12-29-2011 |
