Description

The Blom-Singer VP Large Esophageal & Tracheal Flange is a specialized voice prosthesis designed for individuals undergoing tracheoesophageal puncture (TEP) procedures, particularly those with significantly enlarged or irregularly shaped puncture tracts. This innovative device plays a crucial role in voice rehabilitation for laryngectomized patients, offering a reliable solution to manage leakage around the prosthesis.

Key Features

• Double Flange Design: The prosthesis features both esophageal and tracheal flanges, providing an enhanced sealing mechanism that effectively reduces leakage.
• Material: Constructed from high-quality silicone, ensuring durability and compatibility with the delicate tissues involved.
• Safe Downsizing: Facilitates convenient downsizing from a wider to a smaller diameter prosthesis, enhancing patient comfort and adaptability.

Advanced Delivery System

The device includes a specialized dilator system with a pre-loaded prosthesis and a silicone loop, allowing for precise delivery and unfolding of the tracheal flange. The tapered dilator enables progressive dilation of the TEP tract, while the guidewire and locking mechanism ensure secure attachment during insertion.

Available Sizes

• Diameters: 16FR and 20FR
• Lengths: 4mm, 6mm, 8mm, 10mm, 12mm, and 14mm

Clinical Compatibility

The VP Large Esophageal & Tracheal Flange is compatible with different lengths of the Provox Vega prosthesis, offering seamless integration for healthcare providers. Clinical studies highlight its high success rates in immediate insertion and reduced procedure time compared to traditional methods.

Device Lifespan

The device typically has a lifespan of approximately 8.5 months, with variations due to factors such as biofilm colonization and silicone degradation. Regular cleaning is recommended to manage microbial colonization, although it may not significantly extend the device's lifespan.

Common Complications

• Valve blockage
• Leakage through the silicone valve
• Increased airflow resistance
• Local infection or tissue hypertrophy (less frequent)

Microbial Considerations

The device is prone to biofilm formation by bacteria such as Pseudomonas aeruginosa and Staphylococcus aureus, as well as fungi like Candida species. These factors can influence the prosthesis's longevity and functionality, necessitating careful management and maintenance.

The Blom-Singer VP Large Esophageal & Tracheal Flange stands out as a vital tool in the field of voice rehabilitation, offering tailored solutions for complex clinical needs and contributing to improved patient outcomes.
