Inhealth Tech Blom-Singer® Duckbill Indwelling Voice Prosthesis 16Fr, 10mm L, One-way Slit 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.
