Polymer and Wire Co-Extrusion

Polymer and Wire Coextrusion

Tubing with Wire Inlays and the Coating of Wires Are Playing an increasing role in Medical Engineering

RAUMEDIC is your experienced and competent development partner for applications of coextruded wires in medical engineering. We combine, for example, nitinol, platinum alloys or copper and stainless steel wires with diverse polymer materials. We are also able to realize coatings made of high temperature thermoplastics, such as FEP, PEEK and PTFE Moldflon™, tailored to your particular requirements.

Coated Micro Cables and Wires

  • Ultra thin layer thicknesses up to 0.02 mm (depending on the wire diameter)
  • Wire diameter from 0.05 mm up to 1 mm
  • Dimensions and materials are fully customizable


  • Guide wires
  • Micro cabels, e.g. for forwarding signals in catheters
  • Pacemaker electrodes
  • Corrosion protection for wires
  • Liner for the extrusion of thin walled tubing
  • etc.

Wire Inlay

  • Possibility to fully embed several wires in the tubing wall
  • Wall thickness from 0.6 mm
  • Wire diameter from 0.02 mm to 1 mm
  • Dimensions and materials are fully customizable

Functions and Application Areas:

  • Malleable suction cannulas
  • Nerve stimulation
  • Steerable endoscope
  • Signal forwarding in catheters with measuring functions
  • etc.

In collaboration with you we develop a product tailored to your requirements.

Have You Ever Heard of Intelligent Catheters?

Intelligent catheters offer functions with data transmission features inside and on the patient. They enable the measuring of subsequently listed parameters:

  • Temperature
  • Pressure
  • Oxygen content
  • pH-value
  • Conzentration of a specified ion count
  • Measurement of metabolic parameters
