Abstract
A surgical implant device, including: an implant body; a porous layer disposed adjacent to the implant body, wherein the porous layer includes a lattice of intersecting struts; and a plurality of needle structures protruding from the porous layer opposite the implant body, wherein at least some of the plurality of needle structures traverse the porous layer and are anchored to the implant body. The plurality of needle structures that traverse the porous layer and are anchored to the implant body are coupled to one or more intersecting struts of the lattice. Optionally, some of the plurality of needle structures are spaced apart from the implant body and are anchored only to the porous layer. Preferably, one or more of the implant body, the porous layer, and the plurality of needle structures are formed by an additive manufacturing technique.
