The scaffold is configured to permit the infiltration of human tissue into the plurality of voids. The reinforcement member extends through at least a portion of the scaffold and is configured to resist compressive forces exerted on the scaffold. Also described are embodiments where the void occlusion device is biocompatible, bioresorbable, elastic, and suitable for radio imaging. ## Claims ### Claim 1 A void occlusion device comprising: a scaffold comprising a three-dimensional latticed structure that defines a plurality of voids, wherein the scaffold is configured to permit penetration of human tissue into at least some of the plurality of voids, wherein the scaffold comprises a bioresorbable material composition; and a reinforcement portion of said structure is configured to resist compressive forces if encountered by said scaffold. ### Claim 2 (depends on 1) The void occlusion device of claim 1 wherein the scaffold comprises a material composition that is biocompatible. ### Claim 3 (depends on 1) The void occlusion device of claim 1 wherein the scaffold comprises a strain to failure of at least 20%. ### Claim 4 (depends on 1) The void occlusion device of claim 1 wherein said device is adapted to be visible by x-ray when implanted. ### Claim 5 (depends on 1) The void occlusion device of claim 1 wherein the scaffold comprises aliphatic polycarbonate oligomers. ### Claim 6 (depends on 1) The void occlusion device of claim 1 wherein the scaffold is fabricated from a 3D printable polycarbonate. ### Claim 7 (depends on 1) The void occlusion device of claim 1, wherein the reinforcement portion includes a spiral shaped member. ### Claim 8 (depends on 7) The void occlusion device of claim 7, wherein the latticed structure further comprises a plurality of cells each having a hollow center portion formed by a weave formation of branching arms. ### Claim 9 (depends on 8) The void occlusion device of claim 8 wherein the center portions and the branching arms are curved such that channels are defined through the latticed structure from at least one cartesian direction. ### Claim 10 (depends on 8) The void occlusion device of claim 8 wherein the cell center portions and the branching arms are curved such that channels are formed through the latticed structure from one direction. ### Claim 11 (depends on 8) The void occlusion device of claim 8 further comprising a plurality of pores formed by said branching arms. ### Claim 12 (depends on 1) The void occlusion device of claim 1, wherein the device is comprised of a shape memory material. ### Claim 13 A void occlusion device comprising: a generally disc shaped, three-dimensional scaffold structure adapted to be implanted in a breast, said scaffold having a plurality of voids, and wherein said voids are adapted to accommodate penetration of human tissue into at least some of the plurality of voids, the scaffold comprising: a plurality of layers arranged in a stacked configuration, each layer comprising a plurality of concentric rings; a plurality of members in each layer, extending outward from about a center point of said concentric rings, joining said rings in each of said layers; and, a plurality of connectors which space said layers of rings apart, providing said three dimensional structure, wherein said connectors connect each of said layers to each adjacent layer in the structure, such that the scaffold structure is resistive to compressive forces.
