Claim Text:
1. An intervertebral implant comprising: a first endplate having an upper side and a lower side; 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; and a translation member receivable in the body portion, the translation member including a first angled surface configured to engage a surface of the first endplate and a second angled surface configured to engage a surface of the second endplate, an actuation member having a first end and a second end and threaded portion extending along a portion between the first end and the second end and a non-threaded portion extending between the first end and the second end, wherein the threaded portion of the actuation member does not extend beyond the first angled surface of the translation member and wherein movement of the translation member causes the first angled surface to push against the surface of the first endplate and the second angled surface to push against the surface of the second endplate, thereby causing outward expansion of the first endplate and second endplate, wherein the translation member further includes a third angled surface and a fourth angled surface, and wherein the third angled surface is configured to push against the surface of the first endplate and the fourth angled surface is configured to push against the surface of the second endplate wherein the translation member is coupled to the first and second endplates, wherein movement of the translation member in a first direction causes the first and second endplates to outwardly expand and movement of the translation member is in a second direction causes the first and second endplates to contract towards one another wherein a lip portion of the actuation member contacts a planar surface of the translation member and moves the translation member when the actuation member is rotated.
