Proven to Minimize the Risk of Reintervention1
1. Non-Foreshortening Design
GORE® VIABIL® Biliary Endoprosthesis is the only non-foreshortening fully covered metal stent in the market. This means the implant will not appreciably foreshorten when deployed.* In addition, the GORE® VIABIL® Biliary Endoprosthesis 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.
2. Higher Primary Patency Rates Than the Competition
Patency, or the ability for a stent to remain open and unoccluded, is a crucial characteristic of any Self-Expanding Metal Stent (SEMS). Based on clinical publications, the GORE® VIABIL® Biliary Endoprosthesis maintains higher primary patency than the leading competitor at 3, 6 and 12 months post-deployment, when implanted to manage malignant biliary strictures.5,6 The moderate radial force, low axial force and durable, nonporous ePTFE/FEP liner of GORE® VIABIL® Biliary Endoprosthesis are designed to enhance patency.
3. Optimal Conformance to Ductal Anatomy 2,3,4
The GORE® VIABIL® Biliary Endoprosthesis offers 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. The images to the right demonstrate the effects of low vs. high axial forces on biliary anatomy.
Low Axial Force: GORE®VIABIL® Biliary Endoprosthesis features the preferred combination of low Af and moderate Rf to minimize risk of migration, conforming naturally to the bile duct anatomy.2
High Axial Force: SEMS with high Af do not conform well to curved biliary anatomy. This increases the risk of stent migration, ductal kinking, sludge formation, and/or cholangitis.3
25X Reduction in Migration Rates

4. Significantly Lower Migration Rates than the Market Leaders1
Based on a number of clinical publications, GORE® VIABIL® Biliary Endoprosthesis demonstrates substantially lower migration rates than the competition. Proprietary built-in anti-migration fins gently stabilize the device within the common bile duct, resisting the anatomical forces that could push the device out of place.
