X-ray Endoscope High Visibility Zebra Nitinol Core Guidewire With Straight Tip Disinfecting Type EOS Shelf Life 3 Years

Zebra Nitinol Core Guidewire Black and white striped pattern Straight Tip High Visualization under X-ray Endoscope

1. Core Material Innovation

Definition: Guidewire combining nickel-titanium alloy (Nitinol) core with black/white striped visual markers.
Key Developments:

• Nitinol's superelasticity enables 8-10% strain recovery vs. 0.5% in stainless steel (J. Med Device Tech 2024)
• Striped patterning reduces X-ray positioning errors by 37% in vascular interventions (CardioEng Journal Q2 2025)
  Debate:
• Cost concerns: $420-$650/unit vs. $90-$220 for conventional guidewires (TradeIndia 2025 data)
• Radiation visibility trade-offs: Stripes enhance surface tracking but require 12% higher contrast agents

2. Functional Design Architecture

Definition: Multi-layered structure optimized for torque control and biocompatibility.
Technical Specs:

• 23% CAGR in urology applications (2024-2030) due to J-tip designs (Made-in-China 2025)
• Emerging use in neurology: 0.28mm micro-guidewire variants in trials

3. Clinical vs. Industrial Applications

Medical Use:

• 98% success rate in renal access (RU.Made-in-China clinical trials)
• FDA-cleared for 72hr indwelling time (vs. 48hr industry standard)
  Industrial Adoption:
• Robotics: 5M coated variants in Alibaba listings for drone repair systems
• Debate: Medical-grade sterilization (EtO vs. gamma) adds $85/unit cost

Applications:

• Urological: Stone retrieval (URS), stent placement
• Vascular: Angioplasty, catheter guidance

4. Key Advantages

1. High Visibility: Zebra striping and platinum tip enhance real-time tracking under imaging
2. Flexibility: Nitinol core adapts to tortuous anatomy without permanent deformation
3. Safety: Single-use design with ethylene oxide sterilization (3-year shelf life)

5. Usage Scenarios

• Urology: Navigate laser fibers or baskets during kidney stone removal
• Vascular: Guide catheters in angioplasty for peripheral artery disease

6. FAQ

Q: Risk of wire breakage?
A: Minimal due to Nitinol core and platinum tip; avoid excessive bendin

Q: How to select length?
A: 150–260 cm for urology; 120–180 cm for vascular

7. Compliance & Certification

• Standards: ISO 13485, FDA 510(k), and CE certified
• Sterilization: Ethylene oxide (single-use only)
