This self-expanding biliary stent provides the control and ease of use physicians demand and the outcomes they count on to deliver palliative care to their high risk cases, supported through proven results:

  • Accurate and secure placement: Non-foreshortening* design for precise placement, and Anchoring Fin Technology for reduced migration.
  • Lowest migration rates: 0-1.4% migration rate outperforming BOSTON SCIENTIFIC WALLFLEX Biliary RX Fully Covered Stent migration rates ranging from 0-13%. 1
  • Optimal radial/ axial force balance: The right fit and flexibility help prevent migration and sludge formation.2
  • Proven highest patency: Helps provide a high standard of palliative care for your patients. 3,4
* If deployed as instructed, the endoprosthesis will not appreciably foreshorten.
