  • Publication number: 20120041555
    Abstract: A procedure for making an implant having a textured silicone surface is disclosed. The method may include the steps of providing a conventional mandrel and applying a pre-formed, polymeric mesh sock to the mandrel. The sock is contacted with a silicone dispersion and the silicone dispersion is at least partially cured with the sock in contact therewith. The silicone dispersion is at least partially cured while the sock is in contact therewith and the sock is them removed, for example, by dissolution, to leave a textured elastomeric material useful as a component of a breast implant shell.
