Abstract:
1. An intervertebral implant comprising: a first endplate having an upper side and a lower side, wherein the lower side of the first endplate includes a plurality of ramped surfaces extending therefrom; a second endplate having an upper side and a lower side; a body portion having a first end, a second end, a first side portion connecting the first end and the second end, and a second side portion connecting the first end and the second end, wherein the first end plate and the second endplate are received within the body; a translation member receivable in the body portion, the translation member including a first expansion portion having an angled surface configured to engage one ramped surface extending from the first endplate and a second expansion portion having an angled surface configured to engage another of the ramped surfaces extending from the first endplate; and an actuation member comprising a threaded member, wherein the actuation member is non-threadably engaged with the translation member, wherein rotation of the actuation member causes translational movement of the translation member, and wherein movement of the translation member causes the first expansion portion and second expansion portion to move from the first end of the body portion to the second end of the body portion causing the angled surface of the first expansion portion to push against one ramped surface extending from the first endplate and the angled surface of the second expansion portion to push against another ramped surface extending from the first endplate, thereby causing outward expansion of the first endplate.
