Abstract: A urinal includes a rear wall having a concave inner surface extending downward toward a drain orifice, a pair of sidewalls extending outwardly from the rear wall inner surface in spaced apart relationship, and a user platform positioned between the sidewalls and elevated relative to the drain orifice. The sidewalls are configured such that, when a user is standing on the platform, the user is positioned between the sidewalls.

Abstract: Interbody spinal implants comprise internal sidewalls having a roughened surface topography. The internal sidewalls may be those that surround a substantially hollow implant center, including the sidewalls of a vertical aperture and sidewalls of a transverse aperture. The roughened surface topography comprises macro, micro, and nano features that comprise an amplitude, a peak to valley height, and spacing.

Abstract: An interbody spinal implant including a body, the body comprising: a top surface; a bottom surface; opposing lateral sides; and opposing anterior and posterior portions; the top surface, bottom surface, opposing lateral sides, internal wall surface, and opposing anterior and posterior portions defining a substantially hollow center having a single vertical aperture defining an internal wall surface, the single vertical aperture (a) extending from the top surface to the bottom surface, (b) having a size and shape predetermined to maximize the surface area of the top surface and the bottom surface available proximate the anterior and posterior portions while maximizing both radiographic visualization and access to the substantially hollow center, and (c) defining a transverse rim, wherein at least a portion of the internal wall surface has a roughened surface topography.
