The COOLIEF* Cooled Radiofrequency System â How it Works
A radiofrequency generator transmits a small current of RF energy through an insulated electrode placed within tissue. Ionic heating, produced by the friction of charged molecules, thermally deactivates the nerves responsible for sending pain signals to the brain.
COOLIEF* Cooled RF, known as a minimally-invasive treatment option targeting pain sources, has been clinically documented to provide chronic back pain patients up to 24 months of pain relief, improved physical function, and reduced drug utilization.
- Delivers up to 3.7 times more energy than standard RF.
- COOLIEF* allows for angle independence
- Distally projects 45% or greater beyond the probe tip
- Larger, spherically-shaped cooled RF lesions may increase the probability that target nerves with known nerve path complexity and variability – such as sacral lateral branches, thoracic and cervical medial branches, and the articular sensory branches of the knee and hip joints – will be successfully captured and ablated.

COOLIEF* Radiofrequency System
The COOLIEF* RF System simplifies RF ablation and is designed for Cooled, Standard, Pulsed and Dual Bipolar RF and is comprised of a newly designed RF generator, quad pump and therapy cables.
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.
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.
