Devices and methods for gastrointestinal bypass are described. A gastrointestinal bypass device includes a gastrointestinal cuff and a gastrointestinal sleeve. The cuff may be configured to be attached in the esophagus, and may be sufficiently flexible to expand and collapse to conform with the inside of the esophagus to allow the esophagus to function substantially normally. The sleeve is configured to be coupled to the cuff, and may be made of a material that is floppy or flaccid but does not substantially expand radially.

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.
