GORE® VIABIL® Biliary Endoprosthesis
Fully Covered Metal Stent
GORE® VIABIL® Biliary Endoprosthesis
Maximize control. Minimize migration.
Through its partnership with W. L. Gore & Associates, Inc., Olympus brings a fully covered self-expanding metal stent to healthcare providers caring for patients with malignant biliary obstruction. The GORE® VIABIL® Biliary Endoprosthesis offers a solution for the treatment of malignant biliary strictures by addressing key challenges in biliary stenting and enabling the restoration of bile flow. This device features unique anti-migration fins proven to reduce the risk of reinterventions related to migration†,1, and a non-foreshortening* design that enables precise placement. Its highly conformable construction allows it to adapt to various bile duct anatomies; and the preferred4 balance of radial and axial forces provides the fit and flexibility to help minimize migration.§,4,5
Indications for Use
The GORE® VIABIL® Short Wire Biliary Endoprosthesis is indicated for palliation of malignant strictures in the biliary tree.
Contraindications
The GORE® VIABIL® Short Wire Biliary Endoprosthesis is contraindicated for:
- ALL CARDIOVASCULAR APPLICATIONS
- Ducts less than 5.5 mm in diameter or greater than 9 mm in diameter
Key Benefits
- Anti-migration fins: Atraumatic‡, fully covered anchoring fins securely hold the device within the duct to minimize the risk of migration.*1
- Durable, non-porous Fluorinated Ethylene Propylene (FEP)/expanded Polytetrafluoroethylene (ePTFE) liner: Prevents tissue ingrowth, promotes conformability and supports high primary patency rates.2,3
- Single, continuous wind of Nitinol wire: Designed for conformability and allows for the preferred4 combination of axial and radial forces, naturally following tortuous anatomy.4,5
- Non-foreshortening design* of the endoprosthesis enables accurate deployment positioning.
- Precise placement made easy: Exclusive pull line deployment, radiopaque markers and non-foreshortening* stent design enable accurate delivery.
- Soft, curved tapered tip: Facilitates device delivery.
- Optional transmural drainge holes: Intended to allow for endoprosthesis placement across a branch duct under appropriate anatomical circumstances.
- Short wire delivery system.
