EA/1 - Duckbill Voice Prosthesis, 16 FR, 12mm

This Voice Prosthesis is designed for placement in a passage between the trachea and the esophagus for voice restoration following laryngectomy. The one-way slit 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 changeable device; the patient may insert, remove and clean the device independently.
