We offer a full range of innovative cooled-radiofrequency pain management solutions to treat symptomatic patients experiencing discogenic pain, sacroiliac joint syndrome, thoracic and lumbar z-joint pain. The cooled radiofrequency platform allows for creation of large-volume, spherical lesions for difficult to treat spine anatomy.

The COOLIEF* System - How it Works

The COOLIEF* 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.

COOLIEF* Standard RF




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

COOLIEF* Lesion  

The HALYARD* COOLIEF* Pain Management System includes:


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.

Pain Management Introducer

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


Pain Management Cooled RF Peristaltic Pump Unit

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


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.


Pain Management Radiofrequency Generator

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


SINERGY* COOLIEF* 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 SINERGY* COOLIEF* 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.




TRANSDISCAL* COOLIEF* Pain Management System

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

The TRANSDISCAL* COOLIEF* System uses the 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 TRANSDISCAL* COOLIEF* 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* Cooled Radiofrequency Pain Management System

Perpendicular placement for one-pass, optimal ablation

COOLIEF* System uses the cooled RF platform for lumbar medial branch neurotomy. COOLIEF* 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. COOLIEF* 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* 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* 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.
