Haemostasis Endohepatology Endoscopic Ultrasound Biliary Access Biliary Therapy

Choose from a range of self-expanding metal stents


When treating patients suffering from biliary obstruction, you strive to give them the best possible outcomes—and we strive to give you more device options. To that end, we recently introduced Zilver 635 Biliary Self-Expanding Stents with longer lengths and a redesigned delivery system with improved pushability. The Zilver 635® is available in 4, 6, 8, 10, and 12 cm lengths.

The Zilver 635 features a a slim 6 Fr introducer and balances important traits – such as nonforeshortening nitinol, radial force, flexibility and patency.

And our Evolution® Biliary Controlled-Release Stents are available in 4, 6, 8, and 10* cm lengths. Woven with a single nitinol wire with a platinum core, the Evolution biliary stent is designed to provide uniform radial force, optimal flexibility, and conformability.

Delivered via an 8.5 Fr catheter with kink-resistant Flexor® technology, the Evolution biliary stent combines flexibility for navigating tortuous anatomy and pushability for traversing tight strictures.

In addition to a range of biliary stents, we offer nonbiliary stent options for oesophageal, duodenal, and colonic applications. The Evolution family of stents give you complete control of the stent deployment and the recapturability in all your duodenal, colonic and oesophageal procedures.

*The 10 cm length is only available for the uncovered stent.
