20160374734 | LAMINA IMPLANT AND METHOD - A prosthetic implant for restoring lamina after a laminectomy. The implant is generally a lamina-sized construct having a hollow interior. The lamina removed during the laminectomy may be converted to autologous bone that may then be placed inside the hollow interior of the implant. The implant may then be secured to the spine at the site of the laminectomy so that lamina restoration can occur as the hollow interior of the implant solidifies with bone growth. | 12-29-2016 |
20160374818 | FLEXIBLE ELONGATED CHAIN IMPLANT AND METHOD OF SUPPORTING BODY TISSUE WITH SAME - Implants and methods for augmentation, preferably by minimally invasive procedures and means, of body tissue, including in some embodiments repositioning of body tissue, for example, bone and, preferably vertebrae are described. The implant may comprise one or more chain linked bodies inserted into the interior of body tissue. As linked bodies are inserted into body tissue, they may fill a central portion thereof and for example in bone can push against the inner sides of the cortical exterior surface layer, for example the end plates of a vertebral body, thereby providing structural support and tending to restore the body tissue to its original or desired treatment height. A bone cement or other filler can be added to further augment and stabilize the body tissue. The preferred implant comprises a single flexible monolithic chain formed of allograft cortical bone having a plurality of substantially non-flexible bodies connected by substantially flexible links. | 12-29-2016 |
20160374819 | INTRABODY OSTEOTOMY IMPLANT AND METHODS OF USE - An intrabody implant disclosed and methods of use are disclosed. The implant has an inclined surface, forming a wedge shape having an acute angle adapted to be placed between at least 2 separated portions of a single bony structure (such as a vertebral body). In some embodiments, the implant may be used to support portions of a vertebral body that have been separated surgically as part of a pedicle subtraction osteotomy and to orient the portions at a more predictable lordotic angle. | 12-29-2016 |

20220133498 | EXPANDABLE INTER-BODY DEVICE, SYSTEM, AND METHOD - The present disclosure provides for spinal implants deployable between a contracted position and an expanded position. The spinal implant may include an anterior endplate, a superior endplate, and an inferior endplate operably coupled to a moving mechanism. The first endplate and a second endplate each include at least one bone screw relief. The moving mechanism may include first and second trolleys configured to act against corresponding ramps. The moving mechanism may further include a first set screw and a second set screw opposite the first set screw configured to operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws along a rotation axis, and may also operably adjust an angle of inclination between the first and second endplates upon rotating either one of the first set screw and second set screw along the rotation axis. | 05-05-2022 |
