Patent number: 11819418Abstract: An implantable medical device, such as an intervertebral spacer, may comprise a polymeric component and a metallic component. The metallic component can contain both porous metal and substantially-solid metal. The polymeric material can contain particles of an osseointegrative material. The metallic component can be more protruding toward bone than the polymeric component while having a smaller dimension of roughness than the polymeric component. In embodiments, the pin may press-fit against substantially solid metal. The porous metal may surround solid metal which in turn may surround the pin. The pin may have a press-fit with metal and a looser fit with polymeric component, if the metal components and polymeric components are trapped. A pin may connect superior and inferior metal components by a press-fit. The central opening may be exposed to porous metal and also to substantially-solid metal and to polymer. Specific geometries of implants are disclosed.Type: GrantFiled: January 7, 2021Date of Patent: November 21, 2023Assignee: Omnia Medical, LLCInventors: Troy Schifano, Daniel Johnson

Patent number: 11806059Abstract: An orthopedic fixation system includes an orthopedic implant and an implant retainer. The orthopedic implant transitions between a natural shape and an insertion shape whereby a transition of the orthopedic implant from the natural shape to the insertion shape stores deliverable energy and a transition of the orthopedic implant from the insertion shape to the natural shape delivers stored energy. The implant retainer is configured to engage the orthopedic implant and constrain the orthopedic implant in the insertion shape such that the implant grip prevents a transition of the orthopedic implant from the insertion shape to the natural shape.Type: GrantFiled: July 9, 2021Date of Patent: November 7, 2023Assignee: DePuy Synthes Products, Inc.Inventors: Daniel F. Cheney, Adam T. Knight, Joseph P. Ritz

Patent number: 11806245Abstract: An intervertebral implant is configured to be implanted in an intervertebral space in a first initial configuration. Subsequently, an actuator is configured to be driven in an actuation direction such that the actuator urges the implant to expand along a first expansion direction. Once the implant has been fully expanded along the first expansion direction, the actuator is configured to be further driven in the actuation direction so as to expand the implant in a second expansion direction that is perpendicular to the first expansion direction.Type: GrantFiled: August 26, 2022Date of Patent: November 7, 2023Inventor: Uwe Spetzger

Patent number: 11801148Abstract: The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.Type: GrantFiled: June 15, 2022Date of Patent: October 31, 2023Assignee: Globus Medical, Inc.Inventors: Chad Glerum, Mark Weiman

Patent number: 11793652Abstract: An intervertebral implant includes a body formed as an open lattice structure by a plurality of struts. Some of the struts of the plurality of struts intersect at nodes. The nodes can include an enlarged contact member that extends over the node and at least a portion of the width of some of the struts. Enlarged contact members may have an asymmetrical shape with respect to the intersection of struts. The enlarged contact members can provide improved bone contact for the implant. The plurality of struts can have a cross-sectional shape that includes a flattened portion. The flattened portion of the plurality of struts can provide improved bone contact for the implant. An additive manufacturing process can be used to build the implant in a substantially vertical direction.Type: GrantFiled: August 17, 2020Date of Patent: October 24, 2023Assignee: Institute for Musculoskeletal Science and Education, Ltd.Inventor: James A.
