ABSTRACT:
A voice prosthesis is provided for use in a shunt between the trachea and the esophagus of a laryngectomized patient. The voice prosthesis has a tube-shaped metal part (1) with a funnel-shaped expansion (2) that opens towards its tracheal end. Within the path of the stream of air from the trachea to the esophagus there is provided at least one element (3) that is caused to vibrate by the stream of air passing through the prosthesis, thereby producing an audible tone. With this prosthesis, a laryngectomized patient can produce a much more natural sounding voice than has previously been the case.
