1. A method of making a textured breast implant, the method comprising:
- applying a texturing material onto a mandrel having the shape of a breast implant;
placing a polyurethane foam sheet onto the texturing material;
causing integration between the texturing material and the polyurethane foam sheet by pressing the polyurethane foam sheet into the texturing material;
generating a composite of cured texturing material and polyurethane foam by curing the texturing material after the step of causing integration; and
after the step of generating the composite by curing, removing the polyurethane foam from the cured texturing material by application of a solvent of polyurethane to the composite, to thereby obtain a material having the shape of a breast implant and a surface texture characterized by interconnected pores.

4. A method of producing a textured surface on an implantable breast prosthesis, the method comprising:
-
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 texturing material; applying pressure to integrate the polyurethane foam and the texturing material; curing the texturing material with the polyurethane foam integrated thereto; after the step of curing, removing the polyurethane foam from the cured texturing material by application of a solvent capable of dissolving polyurethane, to thereby obtain a material having the shape of a breast implant and a surface texture characterized by interconnected pores. - View Dependent Claims (5, 9, 10, 11)
