Effective management of biliary strictures with biliary metal stents​

WallFlexTM Biliary RX Stent

Endoscopically placed stents have become the standard of care for biliary drainage with the aim of improving hepatic function, relieving jaundice, and reducing the adverse effects of biliary strictures.​

​They can improve quality of life and allow for palliative chemotherapy in patients with malignancies.​

Multiple factors play a role in the selection of a metal stent.

WallFlex Biliary RX Stents are intended to give you the predictable placement and patency you need as you strive to minimize unplanned patient interventions.

  • Migration resistance
    Looped and flared stent ends designed to help reduce the risk of tissue trauma and stent migration.
  • Tissue in-growth prevention
    Closed cell construction and Permalume™ covered options designed to help resist tissue in-growth.1
  • Flexibility
    Platinol™ Wire construction provides flexibility to aid placement in tortuous anatomies.2
  • Radial force

    Radial force helps maintain stent patency and reduce migration.

  • Removability

    Fully and partially covered stents have an integrated retrieval loop, and may be removed during the initial placement procedure.3

  • Fluoroscopic visualization
    The four fluoroscopy markers and yellow transition zone are designed to aid in stent placement accuracy when deployed using endoscopic visualization.

The WallFlex™ Biliary RX stents and delivery system are designed to face the numerous associated challenges, from the day of the procedure to the long term.

A proven biliary metal stent portfolio. PLUS so much more.

WallFlex Biliary RX Stents are intended to give you the predictable placement and patency you need as you strive to minimize unplanned patient interventions.

2. Flexibility varies by size of stent.

3. In the event of incorrect positioning during the initial stent placement procedure, the partially covered and fully covered stent options may be removed using forceps to grasp the retrieval loop on the end of the stent. Warning: No warranty is made with regard to removability of this device by endoscopic means or otherwise in partially covered or uncovered stents. Indications, contraindications, warnings and instructions for use can be found in the product labeling. The WallFlex Biliary RX Fully Covered Stent System RMV is removable following 12 months of indwell in benign biliary strictures secondary to chronic pancreatitis.

4. The conformability of the WallFlex Biliary PLUS RX Fully Covered Stent System was assessed through axial force measurements in DV bench tests conducted by Boston Scientific, demonstrating that its axial force is lower than that of other self-expandable metal stents, as referenced in the literature by Isayama H, Nakai Y, Hamada T, Yamamoto N, Koike K.

5. The radial force of the WallFlex Biliary PLUS RX Fully Covered Stent System was assessed through radial force measurements in DV bench tests conducted by Boston Scientific, demonstrating that its radial force exceeds the threshold set by other self-expandable metal stents, as defined in the literature by Isayama H, Nakai Y, Hamada T, Yamamoto N, Koike K.
