Cryo Nerve Block Therapy

Providing Several Months of Post-Operative Pain Relief

Cryo Nerve Block Therapy (cryoNB) harnesses the power of cryotherapy to provide a new form of temporary 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’s similar to a local anesthetic.

Cryotherapy was originally developed as a treatment for cardiac arrhythmias. AtriCure consulted with leading pain management experts to develop new techniques for applying cryoNB to nerves, specifically in order to block pain. AtriCure’s cryoICE cryoSPHERE cryoablation probes are sterile, single-use devices intended for use in blocking pain by temporarily ablating intercostal peripheral nerves.
