Key Benefits

  • Maximum Flow Area: Four expandable wings provide a large tip surface area that resists obstruction from blood clots and renal gravel.
  • Reliable Mechanical Retention: Wings expand within the renal pelvis to form a stable internal anchor.
  • No Inflation Valve Required: Eliminates balloon collapse risks or valve failures common in balloon-based tubes.
  • Smooth Insertion over Stiffener: Fully collapses over an internal rigid obturator/stiffener for atraumatic tract advancement.
  • Soft Biocompatible Material: Thermosensitive material adapts to kidney contours, minimizing internal mucosal erosion.
