Patent number: 11026804Abstract: An improved mechanism for expanding or lifting a device in accordance with various embodiments of the present invention is a coaxial screw gear sleeve mechanism. In various embodiments, coaxial screw gear sleeve mechanisms includes a post with a threaded exterior surface and a corresponding sleeve configured to surround the post, the corresponding sleeve having a threaded interior surface configured to interface with the threaded exterior surface of the post and a geared exterior surface. A drive mechanism can be configured to interface with the geared exterior surface of the sleeve, causing a device utilizing such a mechanism to expand or lift between a collapsed configuration and an expanded configuration.Type: GrantFiled: November 5, 2018Date of Patent: June 8, 2021Assignee: SpineX Tec, LLCInventors: Omar F. Jimenez, Nicholas Ransom Powley, Andrew G. Fischer, Yefim Safris

Patent number: 10687963Abstract: An expandable intervertebral cage device includes a first base plate and a second base plate, a proximal block with internal threading that mechanically couples the first base plate and the second base plate, and a distal block comprising an internal passage. The device has exactly two arm assemblies, one on each side. Each arm assembly includes a first arm mechanically coupled to the first base plate and the distal block, and a second arm is mechanically coupled to the second base plate and the distal block. A screw is arranged partially within the internal threading of the proximal block and passes through the internal passage of the distal block, such that rotation of the screw relative to the proximal block causes a change in distance between the proximal block and the distal block, and a corresponding change in the spacing and lordosis of the device.Type: GrantFiled: August 20, 2018Date of Patent: June 23, 2020Assignee: EX TECHNOLOGY, LLCInventors: Omar F. Jimenez, Yefim Safris
