Biliary RX Fully Covered Stent


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.


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.


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.
