<p>A soft tissue prosthesis comprises a shell formed of a polymeric material wherein at least a textured portion of the surface of the shell bears particles of a solid polymeric material that are coated with a layer of polymer dispersion, wherein the textured portion of the surface is characterized by cavities at least some of which are connected beneath the surface. The textured surface has numerous cavities, interstices and passageways or tunnels and is thus referred to as a microporous surface texture. The surface can be formed by applications of polymeric particles and a polymeric dispersion. A method for producing an implant shell having a textured surface is disclosed in which particles of a solid polymeric material are applied to at least a portion of the surface of an implant shell formed at least in part of silicone and having a surface that is uncured or partially cured, the shell is cured and non-adherent solid polymeric material is removed, a polymer dispersion is applied to at least the particle covered portion of the surface to create a coated surface after curing the shell, particles of a solid polymeric material are applied to at least a portion of the coated surface and a polymer dispersion is applied to at least the particle covered portion of the coated surface.</p> |
