The Viabil stent is a revolutionary new addition to the field of biliary endotherapy, offering a novel approach to the management of biliary strictures and blockages. Developed by W. L. Gore & Associates, the Viabil stent is designed to provide controlled and effective biliary drainage, while minimizing the risk of migration and restenosis.
What is the Viabil stent?
The Viabil stent is a fullycovered, self-expanding metal stent that is primarily used for the treatment of biliary strictures caused by a variety of factors, including malignant neoplasms, congenital conditions, and iatrogenic injuries. It is constructed of nitinol, a materials known for its shape memory and superelastic properties, which allows it to adapt to the弯曲 anatomy of the common bile duct.
How does the Viabil stent work?
The Viabil stent is delivered to the site of the stricture or blockage via an endoscope or percutaneously, depending on the location and severity of the blockage. Once in place, the stent expands to fill the entire lumen of the common bile duct, allowing for unimpeded flow of bile. The self-expanding nature of the stent ensures that it maintains its shape and position within the duct, even against strong anatomical forces.
Key Benefits of the Viabil stent
-
Minimal Migration: The proprietary anti-migration fins integrated into the stent design work to gently stabilize the device within the common bile duct, effectively resisting the forces that could cause it to migrate out of position.
-
High Durability: The stent is made of durable materials, including ePTFE/fEP, which has a low coefficient of friction and is resistant to plaque formation. This contributes to the long-term patency of the stent and reduces the need for additional interventions.
-
Controlled Intervention: The Viabil stent provides precise guidance for the endoscope or percutaneous procedure, allowing for precise placement and the minimization of complications.
-
Good Applicability: The Viabil stent is suitable for a wide range of patients, including those with complex bile duct anatomy and those who are unable to undergo surgical reconstruction.
##The Viabil stent represents a significant advancement in the field of biliary endotherapy. Its unique design and proprietary technologies allow for controlled and effective biliary drainage, while minimizing the risk of migration and restenosis. As the only fully covered metal stent with anti-migration technology, the Viabil stent offers a promising alternative to traditional stents and continues to gather attention for its innovative approach to treating biliary strictures.
