Intended Use: Suitable for percutaneous nephrostomy in patients with renal calculi or hydronephrosis.

Components: Dilator, sheath, guidewire, puncture needle, fixator, drainage tube

Product Description:

1. Drainage Tube:
   • Made of silicone material with excellent biocompatibility
   • ≤5mL flat integrated balloon for smooth contraction without folds
   • Facilitates insertion/removal and reduces calyceal injury
2. Dilator:
   • PE material with moderate stiffness
   • Gradual dilation with 2Fr incremental blunt tip design
   • Reduces insertion resistance and minimizes renal bleeding risk
3. Peel-Away Sheath:
   • PTFE material ensures smooth splitting with clean edges
   • Seamless transition with dilator for optimal passage and prevention of renal perforation
4. Puncture Needle:
   • Sandblasted tip for enhanced visibility
   • Clear body markings for precise positioning
   • Sharp penetration with excellent linear advancement
   • Optional diamond/beveled tip configurations
5. Stiff Guidewire:
   • Soft curved tip protects renal parenchyma
   • PTFE coating for low friction coefficient
   • Nitinol core provides strong support and push ability.
