Patent number: 11020241Abstract: A spinal interbody implant includes a two-component cage and expander. The two-component cage, when assembled, accepts the expander through a reverse dovetail configuration between the assembled cage and the expander. The expander has a pair of legs that move within and along lateral channels formed by and between the two cage components for increasing the height of the two cage components relative to one another. The amount of expansion of the cage is determined by the height of the pair of expander legs. The cage accepts different expanders each having pairs of legs of different heights in order to provide different amounts of cage expansion and thus the interbody implant. The front of each expander leg is arch shaped for reception in the lateral channels of the assembled cage and to progressively expand the two cage components relative to one another as the expander is received by the assembled cage.Type: GrantFiled: February 23, 2017Date of Patent: June 1, 2021Assignee: LIFE SPINE, INC.Inventor: Daniel P. Predick
