°AirRay Paddle Electrodes

Our paddle electrodes are designed to provide an electrical interface to the central nervous system. They are the ideal solution for spinal cord stimulation. All contacts are able to record and stimulate.

We offer various designs for your specific application:

  • Number of Contacts
  • Outline and shape of the paddle electrode
  • Contact density
  • Thickness, Stiffness, Softness

°AirRay Research Courtine 2 x 3 + 2 Rhesus Lumbar Array

  • Oblong electrode arrangements
  • Paddle-like outlines 
  • Optional fixation strap for recording and stimulation of the spinal cord.
  • CNS 
  • 8 contacts
  • linear contact arrangement 

Fetz Spinal Cord 8

    • Small strip electrode 
    • recording from and stimulation of the spinal cord
    • developed in cooperation with Eberhard Fetz laboratory
    • CNS
    • 8 contacts
    • linear contact arrangement

Suture Sleeves

Designed to anchor the implanted electrode wires within surrounding tissue. Key benefits of our Suture Sleeves include:

  • Secure Ligature: Prevents electrode movement and displacement
  • Radio-opaque: Clearly visible in all kinds of X-rays
  • Biocompatible: Safe for use in biological environments
