Patent number: 11376134Abstract: An expandable implant movable between a contracted position and an expanded position, is disclosed. In various embodiments, the implant may be defined by a superior endplate and an inferior endplate having proximal ramps and distal ramps disposed on an interior surface thereof, respectively. The expandable body may include a beveled hook portion at a distal end thereof. In various embodiments, upon rotation of a proximal set screw, a proximal wedge may act against the proximal ramps of the superior and inferior endplates and cause the implant to expand at the proximal end. Upon rotation of a distal set screw, a distal wedge may act against the distal ramps of the superior and inferior endplates and cause the implant to expand at the distal end. In some embodiments, both the superior and distal set screws may be rotated simultaneously.Type: GrantFiled: August 2, 2021Date of Patent: July 5, 2022Assignee: WARSAW ORTHOPEDIC, INC.Inventors: Jonathan M. Dewey, Julien J. Prevost, Loic Josse, Bertrand Peultier
