COOLIEF* TRANSDISCAL* Disc Biaclupasty Cooled Radiofrequency System for Discogenic Pain

A Straightforward Solution for Difficult Discogenic Pain

“The advantages of this technique are in relative ease of placement of bipolar electrodes. Cooled RF electrodes may increase the lesion size and facilitate ablation compared to standard RF electrodes.”1
– Kapural & Mekhail, Pain Practice, 2007

For intervertebral disc biacuplasty, bipolar probe placement straight into the disc creates large, reproducible lesion within a significant volume of the disc.

Intervertebral discogenic pain is a major source of axial lower back pain. Thought to be related to nociceptors in the disrupted disc, discogenic pain that does not respond to conservative treatment can be frustratingly difficult to treat with few alternatives available.1,2

For symptomatic patients suffering from discogenic pain, the COOLIEF* TRANSDISCAL* Cooled RF System uses a bipolar approach for intervertebral disc biacuplasty to create a large, reproducible lesion in the posterior and posterolateral annulus. Using revolutionary cooling technology, the dual COOLIEF* Cooled RF Probes coagulate and deactivate nerves in a large volume of the posterior of the disc without risk of excessive heating of tissue.

  • Electrodes are inserted straight inside the disc under fluoroscopy via an introducer for ease of placement, eliminating the challenge of navigating precise placement of a flexible catheter against or between the posterior annular wall.
  • Impedance monitoring assists in identifying annulus and nucleus for confident placement.
  • The COOLIEF* TRANSDISCAL* Disc Biaclupasty Cooled RF System enables the latest advancement in disc biacuplasty—placement of two additional monopolar lesions to help ensure denervation of the entire posterior of the disc (available with advanced generator model, V.4).
  • In a pilot trial, after six months follow up, most patients demonstrated substantial and statistically significant improvements in pain scores and functional capacity postprocedure throughout six months of observations.2 Patients who benefit from disc biacuplasty may avoid invasive surgical procedures.2

The COOLIEF* Cooled RF Pain Management System is a revolution in radiofrequency technology – giving physicians the power of targeted treatment for symptomatic patients, even in difficult to treat spine anatomy.
