Patent number: 11896499Abstract: Expandable fusion devices, systems, and methods. The expandable fusion device includes one or more integrated deployable retention spikes configured to resist expulsion of the device when installed in the intervertebral disc space. The implant may include upper and lower main endplates, an actuator assembly configured to cause an expansion in height of the upper and lower main endplates, and a sidecar assembly including a sidecar carrier, an upper carrier endplate pivotably coupled to an upper spike, and a lower carrier endplate pivotably coupled to a lower spike such that forward translation of the sidecar carrier pushes against the upper and lower carrier endplates, thereby deploying the upper and lower spikes.Type: GrantFiled: December 2, 2021Date of Patent: February 13, 2024Assignee: Globus Medical, IncInventors: Catherine Krawiec, Damien Kahmer, George Yacoub

Publication number: 20230380824Abstract: Distractor and retractor systems and methods of using the same. A pedicle-based distractor assembly may include a base supporting a distraction rack, a pair of moveable arms coupled to the distraction rack, a connector at the end of each arm, each connector having a through-opening, and a pair of distractor elements each configured to attach to a pedicle screw. Each distractor element may be positioned through the through-opening in the respective connector. The distractor elements are modular such that different types of distractor elements, such as headless posts, pre-assembled posts, or minimally invasive towers, are interchangeable with the connectors. The assembly may also include a retractor assembly with a medial retractor blade for retracting soft tissue.Type: ApplicationFiled: May 24, 2022Publication date: November 30, 2023Inventors: Jared Gelber, Damien Kahmer, Robert Ryan, Michael Webster
