Inhealth Blom-Singer 20 Fr. Low-Pressure Voice Prosthesis (Access To Voice) is a silicone one-way flapper valve prosthesis designed for placement in a passage between the trachea and the esophagus for voice restoration following laryngectomy. The one-way valve protects the airway during swallowing and opens under positive pressure so that air crosses into the esophagus to produce voice.

Inhealth Blom-Singer Low-Pressure Voice Prosthesis Features:

1. Employs atraumatic Blom-Singer Gel Cap Insertion System
2. Small diameter prosthesis (16 Fr.) for use in questionably healthy TE wall tissue.
3. Valve (20 Fr.) offers minimal resistance to speech airflow.
4. Optionally increased valve resistance to prevent air ingestion to the stomach.

What is a voice prosthesis?
By creating a small surgical passage just inside the stoma, from the back wall of the trachea into the esophageal wall, a voice prosthesis can be placed into this passage to enable tracheoesophageal speech. The Voice is produced by temporarily blocking the stoma so that exhaled air from the lungs can be directed from the trachea through the prosthesis into the esophagus and then out through the mouth.
Note: The Blom-Singer Low-Pressure Voice Prosthesis is patient-changeable.
