Abstract
A voice prosthesis comprising a tubular body portion, a valve and a valve seat disposed within the body portion. The valve seat is further comprised of a medical grade elastomer containing a dispersion of an antimicrobial agent. This valve seat extends the life of the prosthesis by retarding the growth of microorganisms. The body portion of the prosthesis may also contain an antimicrobial agent at a concentration that is non-toxic to the tissue it contacts.
