Claim Text:
1. An intervertebral implant comprising: a first endplate having an upper surface and a lower surface; a second endplate having an upper surface and a lower surface; a body portion positioned between the first endplate and the second endplate, the 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, second end, first side portion and second side portion define a central opening; a translation member positioned between the first endplate and the second endplate, wherein the translation member is in contact with the lower surface of the first endplate and the upper surface of the second endplate; and an actuation member having a first end, a second end, a threaded portion extending along at least portion thereof from the first end towards to the second end and a non-threaded portion extending from the threaded portion to the second end, the actuation member configured to engage and move the translation member, wherein rotation of the actuation member in a first direction causes translational movement of the translation member such that the translation member pushes against the first endplate and the second endplate, thereby causing the first endplate to expand relative to the second endplate, wherein the threaded portion of the actuation member engages with the body portion and is not engaged with the translation member wherein the translation member includes a first angled portion and a second angled on an upper portion of the translation member and the first angled portion and the second angled portion longitudinally spaced apart wherein the lower surface of the first endplate and the upper surface of the second endplate are positioned in the central opening of the body portion, wherein the translation member is single unitary body and includes a central opening that extends from the first endplate to the second endplate.
