1. An implantable device comprising:
a generally trapezoidal shaped body configured for midline insertion between vertebral bodies of a spine, the body having an upper surface, a lower surface, an anterior portion, a posterior portion, and a pair of exterior sidewalls extending from the upper surface to the lower surface and connecting the posterior and anterior portions, the body further having openings between the upper surface and the lower surface in the exterior sidewalls,
wherein the body comprises a solid perimeter structure and a porous mesh structure contained within the solid perimeter structure, the upper surface, the lower surface and the exterior sidewalls forming the solid perimeter structure, the porous mesh structure being about 50% to about 90% porous being integrated into the solid perimeter structure and being contained within the openings of the exterior sidewalls, with the solid perimeter structure surrounding the porous mesh structure to form a single unitary structure, the porous mesh structure having a repeating geometric unit of cells, the porous mesh structure further being configured to allow bony ongrowth and bony ingrowth therethrough,
wherein an interface between the porous mesh structure and the solid perimeter structure is seamless and devoid of mechanical bonding.
