Why choose Luma Wire Tech for wire for catheters and stents

Wire for catheters and stents

When designing wire for catheters and stents, material performance is not just a specification — it directly impacts visibility, control, and reliability inside the body.

At Luma Wire Tech, our ultra-fine tungsten wires are engineered to meet the demands of minimally invasive medical devices, where precision at the micron level is critical.

Radiopacity for precise positioning

Tungsten’s high density provides excellent radiopacity, ensuring that the wire is clearly visible under fluoroscopy.
This enables accurate placement of catheters and stents, supporting safe and efficient procedures.

Strength at ultra-fine dimensions

Our tungsten wires maintain exceptional tensile strength even at extremely small diameters.
This allows for thinner device designs without compromising mechanical performance.

Optimized for minimally invasive applications

Ultra-fine wire for catheters and stents enables:

  • Improved navigation in complex anatomy
  • Reduced device profile
  • Enhanced procedural control

Engineered surface performance

Our wires are designed with controlled surface characteristics to ensure:

  • Low and consistent friction
  • Reliable interaction with coatings and polymers
  • High precision in assembly and forming

Gold plating options further enhance corrosion resistance and ductility, supporting consistent performance in demanding environments.

Consistency you can rely on

Manufactured in Sweden with full process control, our wire for catheters and stents delivers:

  • Tight tolerances at micro scale
  • High batch-to-batch consistency
