1. A textured breast prosthesis comprising:
a silicone-based breast implant shell comprising a polyurethane-foam-like surface texture embossed over the entirety of said shell, said polyurethane-foam-like surface texture characterized by interconnected pores, wherein said foam-like surface texture comprises a gradient of interconnections between pores, and wherein said gradient of interconnections defining a closed cell foam at one end, and defining an open cell foam at an opposite end, with pores closer to the end defining an open cell foam each having more interconnections than pores closer to the end defining a closed cell foam, wherein the polyurethane-foam-like surface texture is configured to reduce capsular contracture, wherein said textured breast prosthesis is made by the steps of: applying a base coat to a breast implant mandrel; applying to the base coat, a texturing material comprising an uncured silicone dispersion; placing a polyurethane foam sheet onto the silicone dispersion; applying pressure to integrate the polyurethane foam and the silicone dispersion; curing the silicone dispersion with the polyurethane foam integrated thereto; after the step of curing, removing the polyurethane foam from the cured silicone by application of a solvent capable of dissolving polyurethane, to thereby obtain a textured breast implant shell. |
