Abstract
Methods for creating a foam-like texture on an implantable material are provided. More particularly, methods for creating foam-like texture on implantable silicone materials are provided.
Claims11
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.

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.
