Niti-S Biliary Stent

Niti-S Biliary Stent Logo

Conformability where the anatomy bends.

The Niti-S Biliary Stent is an uncovered self-expanding nitinol stent for the palliation of malignant strictures in the biliary tree. Its weaving construction of unfixed cells allows the stent to hold its shape through a curve, maintaining luminal patency in tortuous anatomy.

product features

Built to Follow the Anatomy

Unfixed Cells with Weaving Construction Unfixed cells resemble a chain link fence, allowing the Niti-S Biliary Stent to retain its shape.

High Conformability An optimal combination of radial and axial force to maintain luminal patency in tortuous anatomy.

Precise Placement and Control Minimal foreshortening for accurate positioning.

Radiopaque Markers Three at both ends and two at the midpoint.

the combination

Stenting and Ablation, in One Session

Endobiliary radiofrequency ablation added to stent placement has been associated with significantly better overall survival and stent patency than stenting alone, across 19 trials and 1,946 patients.¹

For interventional radiologists working through an established percutaneous tract, the ELRA™ Endoluminal RF Electrode adds an ablation step to a procedure already underway.
