Overview
Dual-stiffness hybrid ureteral guidewire engineered for precise torque transmission and atraumatic navigation. Combines an ultra-soft 8 cm hydrophilic distal tip, a progressive core transition and a reinforced Nitinol-Zr core for improved pushability and rotational control while maintaining fluoroscopic visibility.


Intended Use

• Ureteroscopic access and negotiation of tortuous or stenotic ureters, management of impacted calculi and procedures requiring laser lithotripsy compatibility.

Key Features & Benefits

• Advanced Dual-Stiffness Design
  • Progressive core construction:
    • Ultra-soft 8 cm hydrophilic distal tip (friction coefficient ~0.02) for atraumatic passage.
    • Transition zone with graded stiffening (approx. 40 g/mm² distal → 120 g/mm² proximal) for controlled advancement.
    • Reinforced Nitinol-Zr core delivering ~30% higher torque response versus standard nitinol wires.
• Precision Visualization & Safety
  • Triple-marker system:
    • Fluorescent green proximal segment for visual depth indication.
    • Radiopaque tungsten-coated distal segment for enhanced fluoroscopic visibility.
    • Spiral stripes for rotational orientation tracking under direct vision.
  • Anti-fracture welding to reduce tip separation risk during aggressive manipulation.
• Optimized for Modern Lithotripsy
  • Laser-resistant PTFE coating: Reflects holmium laser energy (1900–2100 nm) to reduce damage risk.
  • Ceramic-embedded thermal-dissipating distal 2 cm: Limits local heating during prolonged laser activation.
• Clinical Performance
  • High success in accessing severe ureteral tortuosity in multicenter evaluations; low reported perforation incidence in challenging cases.
