ADVANTAGE® Hard Valve LEF (Large Esophagel Flange) is a clinician-placed indwelling voice prosthesis designed to restore tracheoesophageal speech following total laryngectomy. In addition to providing reliable voice rehabilitation, the prosthesis features a large esophageal flange that helps manage periprosthetic leakage by improving retention and creating a more effective seal around the tracheoesophageal puncture (TEP).

ADVANTAGE® Hard Valve LEF Features:

• Restores tracheoesophageal speech following total laryngectomy.
• Features a large esophageal flange (LEF) to help reduce periprosthetic leakage and improve prosthesis retention.
• Incorporates a hard valve assembly that increases resistance to inadvertent valve opening.
• Helps minimise central leakage and unwanted air ingestion caused by fluctuations in oesophageal pressure.
• Silicone valve contains silver oxide as a material preservative to help reduce biofilm formation.
• Includes a titanium body ring for enhanced durability and radiopacity.
• Utilises the Blom-Singer® Gel Cap Insertion Method to support smooth, atraumatic insertion.
• Designed for clinician placement during secondary or replacement TEP procedures.
• Supplied non-sterile for single-patient use.

Additional Options

• Available in 22.5 Fr diameter.
• Available in 6 mm, 8 mm, 10 mm, 12 mm and 14 mm shaft lengths.
• Large Oesophageal Flange (LEF) configuration for patients experiencing periprosthetic leakage.
• Supplied non-sterile for secondary and replacement procedures.
• Compatible with the complete BLOM-SINGER® voice prosthesis care and maintenance system.

NOTE: The Silver Oxide, a known antimicrobial substance, is incorporated into the silicone flap valve of the Blom-Singer Advantage and Dual Valve Indwelling Voice Prostheses as a material preservative, ensuring a longer life-span for the prostheses.
