Large Esophageal Flange - Increased Resistance (LEIR)
Provides a seal to help manage leakage around a voice prosthesis. Also enables downsizing from a wider diameter prosthesis to a smaller diameter. Effectiveness depends on an optimal prosthesis length fit that achieves a snug flange-to-flange seal against the wall surface(s).
Designed to be used in patients in whom conventional voice prostheses open intermittently with fluctuations in esophageal pressures resulting in air ingestion and/or leakage.
