Claim Text:
1. A method of forming a prosthesis having a lattice structure formed thereon, comprising: forming the lattice structure including a plurality of intersecting struts by sequentially sintering a sintering layer of material to a base layer; forming a plurality of substantially uniformly oriented strut ends of the lattice structure at a surface of the prosthesis, wherein the strut ends are angled relative to a remainder of a length of a strut of the lattice structure, wherein the plurality of substantially uniformly oriented struts ends form a plurality of micro-barbs, and wherein the surface of each micro-barb of the plurality of micro-barbs is angled in substantially the same orientation relative to a surface of the prosthesis; and forming at least one macro-barb having a broad end substantially on an exterior surface of the prosthesis and a narrow end extending a distance above the exterior surface, wherein the at least one macro-barb includes a dimension greater than one of the strut ends.
