CLASSIC® Indwelling is a clinician-placed tracheoesophageal voice prosthesis designed to restore speech following total laryngectomy. Its dependable one-way valve allows pulmonary air to flow into the oesophagus for clear, natural voice production while helping to prevent food and liquids from entering the trachea during swallowing. As a result, patients benefit from reliable voice rehabilitation and improved swallowing function. CLASSIC® Indwelling is considered the “baseline” for voice prostheses and is the equivalent option to the Provox 2.

Furthermore, the prosthesis features the proven Blom-Singer® Gel Cap Insertion Method, which enables smooth, atraumatic insertion during primary, secondary, or replacement tracheoesophageal puncture (TEP) procedures. Manufactured from soft, biocompatible medical-grade silicone, it delivers long-term comfort, consistent valve performance, and reliable durability. Supplied sterile and ready for use, it provides clinicians with a convenient solution for efficient prosthesis placement.
