ABSTRACT:
The length of dwelling of a voice prosthesis in the fistula of a patient is extended by supporting the soft hollow body of the prosthesis with an elongated, rigid cartridge and mounting the flapper valve by means of a tab which extends through a slot in the flange of the cartridge. An enlarged cavity in the flange or the body communicates with the slot and receives the leading portion of the tab. The cavity is filled with adhesive to secure the valve to the cartridge.
