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

Patent number: 11871974Abstract: A method of treating scoliosis in a subject includes securing a scoliosis treatment device to first and second locations on the subject's skeletal system, the scoliosis treatment device including a first portion, a second portion moveably mounted relative to the first portion, and an adjustment device disposed on the device and configured to change a distraction force between the first location and the second location, the adjustment device including a rotationally mounted magnetic element configured to move the second portion relative to the first portion in response to rotation of the magnetic element. An external adjustment device is provided external to the subject and is able to adjust the distraction force between the first location and second location.Type: GrantFiled: October 13, 2021Date of Patent: January 16, 2024Assignee: NuVasive Specialized Orthopedics, Inc.Inventors: Blair Walker, Scott Pool, Jay R. McCoy, Arvin Chang

Patent number: 11850160Abstract: An intervertebral fusion cage includes first and second endplate members, first and second ramp members, and an actuator. The first and second ramp members and first and second endplate members have complementary ramp surfaces that engage to expand the height of the fusion cage and to impart a lordotic profile to the fusion cage.Type: GrantFiled: March 26, 2021Date of Patent: December 26, 2023Inventor: Jonathan Melchor

Patent number: 11850163Abstract: An expandable implant may include a superior endplate and an inferior endplate. The superior endplate may have at least one track extending in a proximal-to-distal direction and an inferior endplate may have at least one track extending in the proximal-to-distal direction. An adjusting shim may be disposed within the at least one track to adjust a spacing and angle of inclination of the implant. Some embodiments may include a plurality of tracks for adjusting a spacing and an angle of inclination between the superior endplate and the inferior endplate. Some embodiments may be configured to adjust an orientation of the implant relative to a disc space in both the sagittal plane and the coronal plane. Various embodiments disclosed herein may be used in an Anterior lumbar interbody fusion (ALIF), Transforaminal lumbar interbody fusion (TLIF), or a lateral Lumbar Interbody Fusion (LLIF) procedure, for example.Type: GrantFiled: February 1, 2022Date of Patent: December 26, 2023Assignee: WARSAW ORTHOPEDIC, INC.Inventors: Jonathan M. Dewey, Richard A. Hynes

Patent number: 11826031Abstract: A retractor assembly that includes a base portion in slidable engagement with two or more retractor arms with at least one of the retractor arms releasably securing a retractor blade configured to be anchored to a bone anchor. The retractor blade includes an elongate blade portion with a retractor engagement portion positioned at the proximal end of the elongate blade portion and an anchor mechanism positioned at the distal end of the elongate blade portion. The anchor mechanism includes a first jaw and second jaw configured to engage the bone implant. When closed around or anchored to the bone implant—which may be a shank of a modular screw system—the components of the modular screw are able to be assembled to the shank without adjusting, loosening, or opening the anchor mechanism.Type: GrantFiled: December 8, 2021Date of Patent: November 28, 2023Assignee: Alphatec Spine, Inc.Inventors: David Considine, James Lee, Andrew W. Rajek, Max C. Zemezonak

Patent number: 11759334Abstract: An expandable interbody spacer that is delivered in the anterior approach with adjustable height and end plate angulation (lordosis). The expandable interbody spacer is configured to have an initial collapsed state having a first height suitable for being inserted into an intervertebral space defined by a pair of adjacent vertebrae, and an expanded state having a second height that is greater than the first height. The expandable interbody spacer may be expanded from the initial collapsed state to the expanded state in-situ. The expanded state increases the distance between the adjacent vertebrae and provides support to the adjacent vertebrae while bone fusion occurs and also provides rigid support between the adjacent vertebrae that withstands compressive forces.Type: GrantFiled: June 3, 2022Date of Patent: September 19, 2023Assignee: ASTURA MEDICAL INC.Inventors: Keith Klausman, Thomas Purcell
