Dual-Stiffness Hybrid Guide Wire with Enhanced Torque Control – Next-Gen Urological Access
Intended Use: Complex ureteroscopic procedures requiring both flexibility and pushability, including impacted stones and strictured ureters.
Key Features & Benefits
Advanced Dual-Stiffness Design
- Progressive Core Construction:
- Ultra-Soft 8cm Hydrophilic Tip (0.02 friction coefficient) for atraumatic navigation through tortuous anatomy
- Transition Zone: Gradual stiffening from 40g/mm² (distal) to 120g/mm² (proximal) for controlled advancement
- Reinforced Nitinol-Zr Core: 30% higher torque response vs. standard Nitinol wires
Precision Visualization & Safety
- Triple-Marker System:
- Fluorescent Green Proximal Segment - Visual indicator for safe instrumentation depth
- Radiopaque Tungsten-Coated Tip - Enhanced fluoroscopic visibility (70% less fluoro time required)
- Spiral Stripes - Rotational orientation tracking under direct vision
- Anti-Fracture Welding: Eliminates tip separation risks during aggressive manipulation
Optimized for Modern Lithotripsy
- Laser-Resistant Coating: PTFE layer reflects 99% of holmium laser energy (wavelengths 1900-2100nm)
- Thermal-Dissipating Tip: Ceramic-embedded distal 2cm prevents tissue overheating during prolonged laser activation
Clinical Superiority
- 98% Success Rate in accessing grade 3-4 ureteral tortuosity (200-case multicenter study)
- Zero Reported Perforations in pediatric and post-radiation fibrosis cases
