Abstract:
1. A process of producing an interbody spinal implant having a regular repeating pattern, the process comprising: applying a protective maskant to an entire interbody spinal implant, the interbody spinal implant including a body that is generally oval-shaped in transverse cross section, and comprises a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, a substantially hollow center, anti-expulsion edges at the junction of the anterior portion and the top surface and at the junction of the anterior portion and the bottom surface to resist pullout of the implant once inserted in an intervertebral space, generally rounded and blunt intersections defined along the entire lengths between the top surface and the lateral sides and the bottom surface and the lateral sides, and a single vertical aperture extending from the top surface to the bottom surface, having a maximum width at its center, and defining a transverse rim on the top surface and on the bottom surface, said transverse rim having a posterior thickness greater than an anterior thickness; removing a portion of the protective maskant to expose a base surface of at least one of the top surface of the body and the bottom surface of the body; and applying at least one additive process or subtractive process to at least a portion of the exposed base surface to form a regular repeating pattern, wherein at least one of the top surface and the bottom surface of the interbody spinal implant has the regular repeating pattern and the smooth rounded edge along the top of each lateral side and the top of the anterior portion does not have the regular repeating pattern.
