GORE® VIABIL® is proven to minimize the risk of reintervention1
GORE® VIABIL® Biliary Endoprosthesis is the non-foreshortening fully covered metal stent in the market and remains in the same location throughout deployment, eliminating the need to use a push-pull technique. Physicians can trust that the length and position of the stent will be the same pre-deployment and post-deployment.
Patency, or the ability for a stent to remain open and unoccluded, is a crucial characteristic of any Self-Expanding Metal Stent (SEMS).
The GORE® VIABIL® Biliary Endoprosthesis maintains higher primary patency than the leading stent at 3, 6, and 12 months post-deployment2,3 due to its moderate radial force, low axial force, and durable, nonporous ePTFE/FEP liner.
The optimal balance of low Axial force (Af) and moderate Radial force (Rf), allowing natural conformance of the stent to the bile duct anatomy while maintaining industry-leading primary patency rates.
Optimal Balance of Force: The preferred combination of low Af and moderate Rf to minimize risk of migration, conforming naturally to the bile duct anatomy.4
Low Axial Force: Reduces migration, kinking, sludge formation, and cholangitis.5
