Takes the pain

The universal instrument set for percutaneous nucleoplasty using 4 MHz radiofrequency current application in interventional therapeutic pain interventions on the lumbar spine.

The primary therapeutic goal of nucleoplasty is decompression of nerve structures through volume reduction of the vertebral disk by means of radiofrequency ablation and mechanical removal of materials with rongeurs.

The instrument set is used to create percutaneous access ports to the vertebral disks, for preparation and dissection of tissue using manual instruments, and for coagulation, tissue reduction, and ablation by means of radiofrequency current.

Lumbar Disk Nucleoplasty

While rongeurs are used to remove the material directly from the vertebral disk, the application of radiofrequency current with bipolar TipControl instruments acts on the one hand to reinforce the tissue of the vertebral disk (volume reduction) and on the other hand to destroy the small nerve fibers at the fiber ring of the vertebral disk. The spinal nerves are indirectly decompressed and the destruction of the nerve fibers prevents conduction of pain information to the brain.

Innovative principles for effective nucleoplasty

  • Multi-therapeutic options:

Spinal Decompression

Disc volume reduction

- by manual mechanical resection

- by RF application

Denervation of the annulus structures


  • Endoscopic visualization and documentation
  • Effective and continuous irrigation flow for precise coagulation and cooling of the surrounding tissue
  • Re-usable instrument set

Therapeutic Concept

The centerpiece of effective tissue-preserving coagulation is the Radioblator RF4 radiofrequency generator with a working frequency of 4 MHz.  In combination with the actively articulating TipControl RF Electrode the controlled positioning of the radiofrequency application in the tissue is guaranteed.
