Product Description

Dual-Core Coronary Guidewire Technical Dossier

1. Dual-Core Structural Design
(1) Layered Architecture
|    Component            |   Material & Function                                                                                                                |
|--------------------------|---------------------------------------------------------------------------------------------------------------|
|   Inner Core Wire      | Superelastic Nitinol (SE508), Ø0.005"-0.008", provides shape recovery and kink resistance |
|Outer Support Core  | High-yield stainless steel (316LVM), Ø0.010"-0.012", enhances pushability and torque transmission |
|   Taper Transition     | Laser gradient welding (Tensile strength ≥80gf at transition zone)                     |

(2) Composite Coating System
- Proximal Segment: PTFE coating (2-5μm) for reduced catheter friction  
- Distal Segment: Hydrophilic-hydrophobic hybrid coating (e.g., PVP+silicone) for optimized trackability  

2. Performance Advantages (vs. Single-Core Design)
|           Parameter                |        Dual-Core                                           |         Single-Core                   |
|--------------------------------|----------------------------------------------------|-----------------------------------|
|    Push Efficiency              | +40% improvement (≥92% transmission) |       65-75% typical               |
|    Kink Resistance             |      >500 cycles (1.5mm bend radius)         |       200-300 cycles               |
|    Tip Responsiveness        |        <5° torque delay (1:1.05 ratio)           |       10-15° delay                   |

3. Clinical Applications
(1) Complex Lesions
- CTOs: Outer core provides penetration force (up to 3g tip load), inner core prevents perforation  
- Calcified Tortuous Vessels: Dual-core synergy minimizes whipping effect  

(2) Procedural Compatibility
- Retrograde PCI: Maintains push stability through collateral channels  
- OCT/IVUS Guidance: Radiopaque markers (Ta+Au plating) compatible with intravascular imaging  

4. Critical Manufacturing Requirements
- Concentricity Control: ≤0.001" deviation (laser real-time monitoring)  
- Heat Treatment: Stage-aged (Nitinol: 400°C/1h; SS: 300°C/2h)  
- Coating Curing: UV+vacuum annealing (adhesion ≥1.5N/mm)
