Product Features Technical Specifications

The fully polyurethane-covered membrane completely encloses the nitinol mesh, effectively preventing mucosal tissue ingrowth and significantly reducing restenosis and stone formation.
Naturally expands to its preset dimensions at body temperature, providing conformable wall apposition without the need for additional dilation.
Superelastic properties enable dynamic conformity to the physiological curvature of the ureter—preserving the mucosa while delivering uniform radial support, with minimal migration risk during long-term indwelling.
High-precision delivery catheter, complemented by a urethral protective sheath, compatible with standard endoscopic channels.
Multiple precision radiopaque markers ensure clear intraoperative visualization and accurate deployment positioning.
Fully retrievable endoscopically, preserving flexibility for subsequent treatment, maintaining full procedural control, and reducing device-related complication risks.
