Abstract

Microbial growth on the surface of a valve of a voice prosthesis and optionally the cartridge or ring supporting the valve, is inhibited by providing antimicrobial activity at a level sufficient to retard growth of a microbial film by dispersing an inorganic antimicrobial agent such as silver oxide or an organic antimicrobial agent such as triclosan or butyl paraben dispersed in a medical grade silicone elastomer. The valve, ring or cartridge is in contact with body fluids containing microorganisms and nutrients therefor. The antimicrobial surface can interfere with or inhibit the growth of a biofilm, bacterial layer or a yeast layer. The body of the prosthesis may also contain an antimicrobial surface as long as it is non-toxic to the tissue it contacts. Methods of making such antimicrobial components for voice prosthesis devices are also provided.
