Cryo Nerve Block Therapy

A non-opioid solution for post-operative pain

Cryo Nerve Block Therapy (cryoNB) harnesses the power of cryoICE technology to provide long lasting pain relief for patients who undergo certain invasive cardiac or thoracic surgical procedures. This technology uses a unique freezing method to temporarily block pain signals from nerves in the affected area, providing an effect that is similar to a local anesthetic, but lasts for several months during the patients recovery period.

AtriCure’s Cryo Nerve Block indicated cryoablation probes are sterile, single use devices intended for use in blocking pain by temporarily ablating peripheral nerves in adult patients. cryoNB is also indicated for ablation of peripheral intercostal nerves for patients of at least 12 years of age.

CryoNB nerves regenerating

Once frozen, the tubule structures of the nerve remain intact while the axon degenerates from the site of freezing distally. This is called Wallerian Degeneration.

cryoNB intercostal spaces

Cryo Nerve Block is typically applied at intercostal spaces T3 thru T9, with cryoablation performed above, at, and below the incision level.
