A recently granted patent (Publication Number: US11925565B2) discloses a method for installing an expandable fusion device designed to engage vertebral bodies in the spine. The method involves providing the device with two endplates, each with specific outer surfaces to engage vertebral bodies, along with two ramps that facilitate the expansion of the device. The expandable fusion device can transition between a collapsed and expanded configuration, with the endplates positioned at oblique angles in the collapsed state. The method includes inserting the device into the intervertebral space in the collapsed configuration, ensuring symmetrical expansion of the endplates for effective fusion.

Furthermore, the patent details the configuration of the ramps to mate with the endplates, providing specific angles for mating features to ensure proper engagement. An actuating mechanism, such as a threaded member or snap rings, facilitates the transition from the collapsed to the expanded configuration by moving the ramps towards each other. The expanded configuration results in the endplates being positioned at oblique angles, with the outer surfaces featuring teeth, ridges, keels, or projections for enhanced grip. The method emphasizes the precise design and functionality of the expandable fusion device to achieve successful fusion in the intervertebral space, showcasing innovation in spinal fusion technology.
