Patent ID: 8864839

Claim:
An implant device for humans or mammals comprises: a solid body structure having an exposed surface; one or more selected portions of the exposed surface having a porosity created by bone formation enhancing repeatable geometric 3-dimensional pattern duplicating or replicating the cancellous morphology of under-modelled pre-cancellous bone mimicking a marine or sea mammal bone structure wherein the repeatable geometric 3-dimensional pattern is repeatably placed on portions of the exposed surface to create a substantially continuous network having voids having a medium width of 500 to 800 microns formed as a trabecular structure which enhances bone formation, the voids of the substantially continuous network extend to a depth of 150 microns or less from the one or more portions of the exposed selected surface having the 3-dimensional pattern providing the depth of the 3-dimensional pattern, the depth being the distance the pattern penetrates into the body structure to produce the repeatable 3-dimensional pattern for enhancing bone formation of about 150 microns or less.
