Tools designed to support your biliary procedures from access to therapy.


We understand that accessing the ductal system can be one of the most difficult aspects of your procedures. We know, too, that wire guide tip flexibility is one of the keys to achieving access. So, we’ve carefully considered what we’ve learned from serving the needs of interventional radiologists during the last 50 years and applied that expertise specifically for endoscopic retrograde cholangiopancreatography (ERCP). The result? The Acrobat® 2 Calibrated Tip Wire Guide—one of the most flexible-tipped wire guides on the market.¹ (See it in action in the clinical case video below.)

What’s more, the Fusion® OMNI™ Sphincterotome with DomeTip® and the D.A.S.H.™ Sphincterotome with DomeTip can provide you with procedural efficiency and consistent performance in a wide variety of clinical situations. Both the Fusion OMNI and the D.A.S.H. are used for cannulation of the ductal system and for sphincterotomy.

    Therapeutic solutions after gaining access

    When treating patients who are 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 self-expanding stent features non-foreshortening nitinol, a push-pull delivery system, and a 6 Fr catheter.
    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.
