Product overviewReinforced nitinol ureteral access sheath designed for retrograde intrarenal surgery (RIRS) to provide stable access and scope protection in tortuous ureters. Available in clinical 12Fr and 14Fr sizes and multiple lengths for optimized irrigation and fragment evacuation.
Key technical advantages- 180° kink resistance: braided nitinol‑polyurethane composite (ISO 10555-5)
- Dual-size optimization:
- 12Fr (3.6 mm ID): 38 L/min irrigation flow
- 14Fr (4.2 mm ID): enhanced stone fragment clearance
- Ultra-smooth lining: PTFE interior (approx. friction coefficient 0.05)
- Proven clinical performance: reported ~97% success in difficult access cases
Technical specifications- Length options: 35 cm / 45 cm
- Visibility: radiopaque markers every 5 cm
- Coating: hydrophilic (~5 µm)
- Compatibility: compatible with standard ureteroscopes
- Sterilization: EO sterilization
