Takes the pain

PERCULINE nucleo is the universal instrument set for percutaneous nucleoplasty utilizing 4 MHz radiofrequency energy application in therapeutic pain interventions in 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 nuclear material with rongeurs.

The reusable instrument set is used to create a percutaneous access port to the vertebral disk, for preparation and removal of tissue using manual instruments, and for coagulation, tissue reduction, and ablation by means of radiofrequency energy.

Lumbar Disc Nucleoplasty

While rongeurs are used to remove the material directly from the vertebral disk, the application of radiofrequency energy with bipolar TipControl instruments acts to both ablate the tissue of the vertebral disk (volume reduction) and to disrupt the small nerve fibers at the fibrous ring of the vertebral disk. The spinal nerves are therefore indirectly decompressed and the disruption of the nerve fibers prevents conduction of pain signals to the brain.

Innovative principles for effective nucleoplasty

  • Multi-functional options:

Spinal Decompression

Disc volume reduction

- by manual mechanical resection

- by RF application

Denervation of the annulus structures


  • Endoscopic visualization for verification and documentation
  • 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.
