Publication number: 20230248536Abstract: An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.Type: ApplicationFiled: April 17, 2023Publication date: August 10, 2023Inventors: Jason Gray, Daniel Davenport, Chad Glerum, Duncan Sibson, Jason Pastor, Derek Martzall

Publication number: 20190262041Abstract: Devices and methods for coupling first and second adjacent vertebrae. The device includes a first coupling element and a second coupling element. The first coupling element has a first body portion for receiving a first bone fastener and an elongate rod portion extending transversely from the first body portion. The second coupling element has a second body portion for receiving a second bone fastener and an extension portion extending transversely from the second body portion. The extension portion defines a recess sized and configured to receive the rod portion of the first coupling element. When unlocked, the rod portion is moveable in the recess to allow for rotational and translational movement of the first and second coupling elements. When locked, the relative position of the first and second coupling elements is fixed.Type: ApplicationFiled: May 13, 2019Publication date: August 29, 2019Inventors: Jeff Nichols, Aditya Ingalhalikar, Khiem Pham, Michael Harper, Devjeet Mishra, Derek Martzall
