1. A method for forming an elastomeric porous material, the method comprising the steps of:
a) applying a silicone elastomer matrix material to a contoured mold having the shape of a breast implant; b) applying a fibrous covering to the silicone elastomer matrix material on the contoured mold wherein the fibrous covering comprises polymer fibers having an average thickness between about 100 μm and 1000 μm; c) treating the silicone elastomer matrix material having the fibrous covering to cure the silicone elastomer matrix material on the mold; and d) removing the fibrous covering from the cured silicone elastomer matrix material, wherein fibrous covering removal results in a porous silicone elastomer material defining an array of interconnected tunnels and channels, the porous silicone elastomer material having a thickness of at least 300 μm, and the porous silicone elastomer material is in the form of a breast implant shell.
