Patent attributes
An expandable implant having superior and inferior endplates is disclosed. The superior endplate includes a first inside surface having a crossbar extending in the widthwise direction. The inferior endplate includes a second inside surface having a medial support structure, a threaded core, and a receiving cavity. A threaded locking screw may be disposed in the threaded core, and a proximal saddle may be disposed in the receiving cavity. In various embodiments, in a locked position, a relative position of the inferior endplate with respect to the superior endplate is fixed, and the threaded locking screw directly contacts, pushes, applies a force against, and/or compresses, the proximal saddle, the proximal saddle directly contacts, pushes, applies a force against, and/or compresses the crossbar, the crossbar directly contacts, pushes, applies a force against, and/or compresses the distal saddle, and the distal saddle directly contacts and is engaged against the second interior distal wall.
