Abstract

An implantable medical device, such as an intervertebral spacer, may comprise a polymeric component and a metallic component. The metallic component can contain both porous metal and substantially-solid metal. The polymeric material can contain particles of an osseointegrative material. The metallic component can be more protruding toward bone than the polymeric component while having a smaller dimension of roughness than the polymeric component. In embodiments, the pin may press-fit against substantially solid metal. The porous metal may surround solid metal which in turn may surround the pin. The pin may have a press-fit with metal and a looser fit with polymeric component, if the metal components and polymeric components are trapped. A pin may connect superior and inferior metal components by a press-fit. The central opening may be exposed to porous metal and also to substantially-solid metal and to polymer. Specific geometries of implants are disclosed.

Dependent claims

An implantable device,

said device having a device first bone-facing surface and an opposed device second bone-facing surface and having a central opening extending from said device first bone-facing surface to said device second bone-facing surface,
said device comprising a metallic component and a remainder of said device, said metallic component and said remainder of said device being mechanically joined to each other, said metallic component having a metallic component first bone-facing surface and an opposed metallic component second bone-facing surface,
wherein said metallic component comprises an anchoring screw hole passing through an anterior surface of said metallic component and continuing at least partially through either said metallic component first bone-facing surface or said metallic component second bone-facing surface, said anchoring screw hole having an anchoring screw hole internal surface,
wherein either said metallic component first bone-facing surface or said metallic component second bone-facing surface comprises both a substantially-solid metal region and a porous metal region, and
wherein said porous metal region is located such that (a) no portion of an anchoring screw hole internal surface comprises any of said porous metal region;
or (b) no more than 10% of said anchoring screw hole internal surface comprises said porous metal region.
