Inhealth Blom-Singer Duckbill Voice Prostheses, The Duckbill is a 16Fr silicone, one-way slit valve prosthesis designed for placement in a passage between the trachea and the esophagus for voice restoration following laryngectomy. The one-way valve of the Duckbill protects the airway during swallowing and opens under positive pressure so that air crosses into the esophagus to produce voice.
