16 French Duckbill Voice Prosthesis, 18mm

 Blom-Singer® Duckbill Indwelling Voice Prosthesis 16Fr, 18mm L, One-way Flapper Valve

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.

• The Duckbill is a patient-maintained device; the patient may insert, remove and clean the device independently.
