 I. Core Features (Why Intervene with All Nickel-Titanium Guidewires)

• Superelasticity: Maximum recoverable deformation of 6%, automatically rebounds after bending, can navigate complex vascular branches without plastic deformation

• Shape Memory: The preset shape is restored at body temperature (37°C), ensuring the bent tip remains unchanged during surgery

• Low stress hysteresis: Smooth torque transmission, precise rotational control, and minimal push resistance

• MRI-compatible, corrosion-resistant, and biocompatible, meeting the mandatory medical standards ASTM F2063 / GB24627

• Regular phase transition temperature Af: adjustable from 0 to 35°C, commonly used for medical guidewires with Af=25±2°C

 II. Mainstream Specifications (Industry Dual Standards in Inches/MM)

 1. Diameter (core wire material)

Ultrafine neuro/coronary microguidewires: 0.05~0.36 mm (0.002"~0.014")

Peripheral, Urological, and Gastrointestinal General Use: 0.43–0.89 mm (0.018"–0.035")

Coarse support guide wire: 1.0~1.5mm

Customizable tolerance of ±0.001mm for precision grade

 2. Standard Length of Finished Guidewires

150cm, 180cm, 260cm, 300cm, with head types: soft head (Floppy), extra soft head (Extra Floppy), and hard support head

 3. Surface treatment (essential for guide wire and core wire)

Bright electrolytic polishing: High-end coronary and neuro-interventional applications, with no oxide layer and easy hydrophilic coating adhesion

Light Oxidized Blue/Gold Film: Conventional Urological and Peripheral Guidewires, High Cost Performance

Black oxide scale: industrial test samples, non-implantable consumables

 III. Clinical Application Classification

• Coronary guidewire: 0.014" ultra-fine nitinol core with hydrophilic coating, used for coronary artery stenosis and PCI procedures

• Neurointerventional guide wire: 0.008"～0.010" ultrafine wire, extremely low hardness, suitable for tortuous cerebrovascular pathways

• Peripheral vascular guidewires: for lower limbs and carotid arteries, combining support force with flexibility

• Ureteral guidewire: Strong bending and rebound for ureteral lithotripsy and nephrostomy

• Digestive/Biliary Guidewires: ERCP, Bile Duct Dilation

• Minimally invasive puncture guide wire: Biopsy and drainage channel establishment
