Patent number: 11944551Abstract: A joint spacer therapeutically maintains separation of bones of a joint. A carriage is slideably retained within the frame and has at least one ramped surface. An actuator screw is threadably engaged with the frame, and rotatably connected to the carriage, to cause the carriage to slideably move within the frame when the actuator screw is rotated. First and second endplates engage the bones of the joint, and each has at least one ramped surface that is mateable with the ramped surface of the carriage, whereby when the carriage is slideably moved by rotation of the actuator screw, the endplates ramped surface slides against the carriage ramped surface to cause the endplates to move along an axis transverse to the longitudinal axis of the frame, to increase the height of the spacer. Piercing elements are connected to the carriage to pierce bone of the joint when the carriage is moved.Type: GrantFiled: May 18, 2021Date of Patent: April 2, 2024Assignee: Globus Medical, Inc.Inventors: Jody L.

Patent number: 11883080Abstract: Implants, systems, and methods of reverse dynamization. The implants, such as expandable spinal implants, bone plates, and intramedullary nails, are securable to bone. The implant may have a moveable component creating a semi-rigid configuration to allow for micro-motion of the bone for a period of time. The moveable component is changeable, for example, based on material properties, change of state, or mechanical or electrical operation, to a static condition creating a rigid configuration to prevent subsequent movement of the bone. The reverse dynamization implants may be used to accelerate bone healing and obtain superior bone fracture healing.Type: GrantFiled: July 13, 2022Date of Patent: January 30, 2024Assignee: Globus Medical, IncInventors: Catherine Krawiec, Peter Evans, Chad Glerum

Patent number: 11850161Abstract: A spacer separates bones of a joint using a driver tool having a threaded shaft. The spacer has a superior endplate with inferior facing ramps, and an inferior endplate with superior facing ramps. Two bearings are positioned between the endplates, each bearing has superior facing ramps which mate with the inferior facing ramps of the superior endplate, and inferior facing ramps which mate with the superior facing ramps of the inferior endplate. One bearing has a threaded aperture, and the other a thrust surface. A threaded shaft is threaded into the threaded aperture to push against the thrust surface to drive the bearings apart. As the bearings move apart, the mated ramps slide against each other to drive the superior and inferior endplates apart.Type: GrantFiled: November 16, 2021Date of Patent: December 26, 2023Inventors: Tyler Hessler, Chad Glerum, Mark Weiman, Albert Hill, Myles Sullivan
