Demonstrated low migrations
Fully covered anti-migration fins securely hold the device within the duct to minimize the risk of migration, with a reported 0.0–1.4% migration rate range. This outperforms BOSTON SCIENTIFIC WALLFLEX Biliary RX Fully Covered Stent migration rates, which ranged 0–13%.1
Higher primary patency
GORE® VIABIL® Biliary Endoprosthesis offers substantiated evidence in studies that demonstrate sustained long-term patency. Clinical performance demonstrates GORE® VIABIL® maintains higher primary patency than the leading competitor at 3, 6, and 12-months.2,3 Improved long term patency can mean an improved quality of life for patients.
Optimal Conformability
GORE® VIABIL® Biliary Endoprosthesis offers the optimal balance of radial and axial forces, providing the right fit and flexibility to help prevent migration and sludge formation.4,5
Durable Liner
A durable, non-porous FEP/ePTFE liner prevents tissue ingrowth, promotes conformability and supports superior primary patency rates.
Backed by the CONMED Biliary Assurance Program
With a 0.2% average reported migration rate, we’re so confident in these outcomes that we will replace it if a migration occurs.6,7
