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.
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
