Longitudinally Reinforced Tubing / Composite Tubing

Composite Tubing | Longitudinal Reinforcement

Filament reinforced tubing offers higher performance for applications which require advanced tubing properties. DUKE Extrusion can add longitudinal reinforcement to your tubing to reduce axial elongation (stretching) and/or to provide preferential bending characteristics for a wide range of applications, including:

  • Deflection catheters
  • Implant delivery catheters
  • Electrical leads
  • Sensors
  • Stretch limiting features

Longitudinal reinforcement can also be combined with tip shaping, and can be used to create a variety of fixed curves in your tubing extrusion.

Materials for Composite Tubing

We can add a number of longitudinal reinforcement filaments to any custom extrusion to form composite tubing. We use an array of materials, including:

  • Metallic wire – round or flat
  • PEEK
  • Kevlar™
  • PEN
  • Nylon
  • PET
  • Liquid crystal polymer (LCP)
  • Carbon fiber
  • Polymeric filaments

Custom Options for Filament Reinforced Tubing

Longitudinal reinforcement can be combined with a number of other tubing options, including coil and wire reinforced tubing, multi-lumen tubing, braiding, and PTFE lined lumens. When combined with braided extrusions, longitudinal reinforcements are known as zero angle elements and can be added above, below, or woven through the braid.

Longitudinally Reinforced Tubing

While plastic is molten and being formed into a tube, we add a filament or wire. Some examples of uses for filaments in tubing are electrical conductors to carry signals, or tethers to prevent the tube from stretching. DUKE Extrusion’s composite tubing can help improve longevity and performance of medical devices.
