Embodiment Construction

[0057] In general, and not intended to be limiting, one aspect of the present invention relates to improved medical implants comprising, for example, at least the following structures: a primary structure formed of metal; and At least one needle-dense, metallic surface portion formed on at least one outer portion of the primary structure, the at least one surface portion being positioned such that it engages the patient's bone when the implant is implanted in the patient . Such a metal surface portion densely covered with needles may contain, for example, an aggregate of at least 50, 100, 200, 500 or more needles, and may further be characterized by at least one, two, three of the following One, four, five or more characteristics characterized by: (a) the needles in the assembly are all oriented substantially perpendicular to the surface portion; (b) the needles in the assembly are all in substantially the same oriented in a direction that is not perpendicular to the surface ...

Abstract

A surgical implant device, comprising: a body portion; and one or more surfaces comprising a plurality of protruding structures; wherein the body portion and the one or more surfaces comprising the plurality of protruding structures are integrally formed. The one or more surfaces comprising the plurality of protruding structures are formed by an additive manufacturing process. The plurality of protruding structures comprise a plurality of needles. Optionally, the surgical implant device comprises one of an anterior lumbar interbody fusion cage, a posterior lumbar interbody fusion cage, a transforaminal lumbar interbody fusion cage, an oblique lumbar interbody fusion cage, a cervical cage, and a bone screw.
