Cooled Radiofrequency Products

Pain Management Solutions

Halyard Health COOLIEF* Cooled Radiofrequency (RF) System is a revolution in radiofrequency technology as the cooled radiofrequency platform allows for creation of large-volume, spherical lesions - giving physicians the power of targeted treatment for symptomatic patients, even in difficult to treat spine anatomy.

With the addition of COOLIEF* Cooled RF System, Halyard now offers a complete portfolio of cooled radiofrequency treatment for all segments of the spine... from the cervical facet joint to the sacroiliac (SI) joint.

The COOLIEF* Cooled Radiofrequency System - How it Works

The COOLIEF* Cooled RF pain management system is indicated for use to create RF lesions in nervous tissue. The sterile, single-use probe is inserted through an introducer into or near nervous tissue. RF energy heats the tissue while circulating water moderates the temperature in close proximity to the electrode or active tip. This combination creates large volume lesions without excessive heating at the electrode.

Standard RF




Cooled RF Lesion

Without cooling - the size of the lesion is limited by the heat generated in adjacent tissue

The larger heating distance and greater depth of lesioning are "an important consideration in light of the individual anatomy variation in location and quantity of nerves."1

The COOLIEF* Cooled RF Pain Management System includes:


COOLIEF* Cooled RF Pain Management Radiofrequency Probe

  • Probe includes a 4-foot connecting cable and tubing extension to reach out of the sterile field. These are connected to the generator and peristaltic pump unit for RF energy delivery and internal cooling.
  • A thermocouple in the probe measures cooled electrode temperature throughout the procedure.
  • A radiopaque marker is located at the proximal end of the active tip. This marker defines the lesion location under fluoroscopy, confirming position and enhancing visualization.

COOLIEF* Cooled RF Pain Management Introducer

The sterile, single use introducer provides a path for the probe to the nervous tissue.



COOLIEF* Cooled RF Pain Management Cooled RF Peristaltic Pump Unit

The pump unit is used to circulate cool sterile water during lesion formation.



COOLIEF* Cooled RF Pain Management Tube Kit

The sterile, single use tube kit is used for closed-loop circulation of sterile water through the probe. It includes a burette to hold water, connected to tubing that is inserted in the pump unit.



COOLIEF* Cooled RF Pain Management Radiofrequency Generator

The Pain Management Generator PMG-115-TD and PMG-230 (V. 2 or higher) are the only RF generators compatible with COOLIEF* Cooled RF Pain Management Systems



COOLIEF* SINERGY* Sacroiliac Cooled Radiofrequency Pain Management System

An innovative RF treatment for chronic sacroiliac joint pain

The fundamental challenge of treating SIJ pain is capturing the afferent lateral branches coursing between the painful SI region and the posterior sacral foramina. The COOLIEF* SINERGY* Sacroiliac Cooled RF Pain Management System enables placement of large volume lesions, which compensate for the known variability of nerve location and running course of the lateral branches of the posterior rami.



COOLIEF* TRANSDISCAL* Disc Biacuplasty Cooled Radiofrequency Pain Management System

Bipolar, Cooled RF for intervertebral disc biacuplasty - the next generation of treatment for discogenic pain

The COOLIEF* TRANSDISCAL* Disc Biacuplasty Cooled RF Pain Management System uses the COOLIEF* Cooled RF system with a bipolar approach to deactivate nerves to treat symptomatic discogenic pain. Under fluoroscopy, two introducers are placed bilaterally in the posterolateral disc, and then two COOLIEF* TRANSDISCAL* Cooled RF Probes are inserted. The water-cooled probes deliver RF energy with enough power to heat a larger volume of disc tissue while eliminating overheating of adjacent tissue. The result is a large, reproducible lesion within a significant volume of the posterior of the disc.




COOLIEF* Lumbar Cooled Radiofrequency Pain Management System

Perpendicular placement for one-pass, optimal ablation

The COOLIEF* Lumbar Cooled RF Pain Management System uses the cooled RF platform for lumbar medial branch neurotomy. The COOLIEF* Cooled RF Pain Management System enables placement of a large-volume lesion encompassing the medial branch nerve in one pass, eliminating the need for multiple passes. Many patients may fail standard RF treatments, or have a challenging anatomy. The COOLIEF* Cooled RF Pain Management System enables perpendicular placement allowing "gun-barrel" access to target the nerve, compared to standard RF, in which parallel placement to nerve or multiple-pass lesioning is required to achieve optimal ablation.




COOLIEF* Thoracic Cooled Radiofrequency Pain Management System

Cooled RF technology overcomes the challenge

A major challenge in treating chronic, thoracic facet pain comes from the variable course of the medial branch nerve, particularly in the mid-thoracic levels. The COOLIEF* Thoracic Cooled RF Pain Management System overcomes the challenge of the variable nerve course by enabling placement of a large-volume, reproducible lesion, of the size and position that can account for the medial branch variability.



COOLIEF* Cervical Cooled Radiofrequency System

An innovative option for helping resolve cervical facet joint pain

Cervical pain is the third most common pain in the spine with more than 44 million patients afflicted annually. More than 200,000 turn to cervical injections for pain relief; however, cervical pain is often difficult to treat through diagnostic and therapeutic nerve blocks due to nerve course variability and the difficult anatomy of the spine.

The COOLIEF* Cervical Cooled RF System is designed to address the unique anatomy of the cervical joints by employing water-cooled technology anatomically tailored to offer relief in the cervical region. By delivering large volume lesions where anatomy and nerve path are variable, the lesion conforms around ridges and within crevices on irregularly shaped surfaces, enhancing the ability to capture the nerve.
