High-precision Variable Durometer Tubing
PT&C™ specializes in providing high-precision variable durometer tubing and assembly solutions for manufacturers of catheters, stent delivery systems, and other minimally invasive diagnostic devices.
The high-precision variable durometer tubing features a linear hardness transition from a soft distal end to a rigid proximal end, achieved through one-step extrusion processing. This eliminates the need for traditional methods that use a melting machine to fuse tubes of different hardness levels, forming the outer insulation layer of a catheter. As a result, it significantly reduces costs and improves product yield.
These tubes offer flexible customization in terms of performance, coating color, specifications, and inner/outer diameter options, meeting the diverse application needs of high-end medical devices.
Currently, variable durometer tubing has been successfully applied in coronary stent delivery systems, heart valve delivery systems, peripheral vascular delivery systems, and neurovascular interventional catheters.
Key Advantages of Variable Durometer Tubing
Performance
- Gradual Hardness Transition – Provides a smooth, linear transition from a soft distal end to a rigid proximal end, optimizing flexibility and pushability.
- One-Step Extrusion Process – Eliminates the need for bonding or welding different hardness segments, improving structural integrity.
- Enhanced Kink Resistance – Reduces the risk of kinking or buckling, ensuring better catheter performance during navigation.
- Improved Torque Control – Enables precise maneuverability for minimally invasive procedures.
- Biocompatibility – Manufactured using medical-grade materials, ensuring safety for long-term implantation or contact with bodily fluids.
Delivery
- Reduced Production Costs – One-step extrusion lowers material waste and labor costs compared to traditional assembly methods.
- High Yield & Consistency – Automated processing improves reproducibility and minimizes defects.
- Faster Production Cycles – Streamlined manufacturing reduces lead time for medical device production.
- Scalability – Suitable for high-volume production while maintaining precision and quality.
Customization
- Variable Inner & Outer Diameters – Designed to meet specific catheter design requirements.
- Multiple Material Options – Available in Pebax®, TPU, Nylon, EFEP, and other medical-grade polymers.
- Custom Coatings & Colors – Options for hydrophilic, antimicrobial, and radiopaque coatings for enhanced visibility and performance.
- Segmented or Continuous Hardness Gradation – Allows for precise control of mechanical properties.
- Multi-Lumen or Reinforced Structures – Additional features like braid or coil reinforcements can be incorporated.
