The Avanos Medical CERVICOOL* COOLED RF System uses revolutionary cooling technology for pain relief. Technologically advanced Compared to Standard RF, CERVICOOL* water-cooling technology allows for higher power delivery and a larger volume of treated tissue, without increased risk of adjacent tissue damage. Accuracy Larger lesions increase the probability of capturing the target medial branch nerve, eliminating the need for multiple passes. Ease-of-use The shape of the lesion allows perpendicular, oblique or parallel approaches towards the target structure. The lesion conforms around ridges and within crevices on irregularly shaped surfaces, enhancing your ability to capture the nerve.
