Claim 10:
11. A soft tissue reconstruction implant for insertion into a patient, the implant comprising:
a plurality of repeated unit cells connected to each other to form a three-dimensional lattice structure, a unit cell of the plurality of repeated unit cells being a basic unit of the three-dimensional lattice structure, wherein the three-dimensional lattice structure comprising a resting volume of the implant,
wherein the plurality of repeated unit cells are arranged to form a porous network of the three-dimensional lattice structure, and wherein the three-dimensional lattice structure is a reversibly compressible three-dimensional lattice structure, wherein the bulk porosity of the three-dimensional lattice structure of the implant is at least 50%;
a plurality of surface filler portions arranged to form a plurality of surface filler columns at an outer surface region; and
a plurality of open columns at the outer surface region that are free from surface filler portions;
wherein the three-dimensional lattice structure comprises:
a first outer surface region of the implant comprising a first surface curvature; and
a second outer surface region of the implant comprising a second surface curvature,
wherein the second outer surface region of the implant is contiguous to the first outer surface region of the implant at a perimeter of the first outer surface region, and
wherein a geometry of the second outer surface region represents a geometry of a breast region, to be constructed by the implant;
wherein the second outer surface region comprises:
an upper pole portion comprising a geometry of an upper portion of the breast to be constructed by the implant, and
a lower pole portion comprising a geometry of a lower portion of the breast to be constructed by the implant,
wherein the upper pole portion and lower pole portion are coincident at an apex region of the second outer surface region of the three-dimensional lattice structure,
wherein a pore size of openings at the second outer surface region of the implant increases from 0.5 mm at the upper pole portion to 2 mm or to 5 mm at the apex region of the second outer surface region, and from 0.5 mm at the lower pole portion up to 6 mm, or up to 8 mm, or up to 10 mm towards the apex region of the second outer surface.
