Cryoanalgesia is a method of temporarily relieving pain by cryo ablating the affected nerve, causing an interruption of pain impulses to the brain. For cardiac and thoracic surgery patients, the pain impulses are blocked by ablating the intercostal nerve bundle(s), thereby alleviating the pain associated with a thoracotomy incision. When applied appropriately, cryoanalgesia can relieve pain for several days and in some cases weeks.
“The expanded indication provides patients and physicians with options to manage the pain associated with a thoracotomy,” said Mike Carrel, president/CEO of AtriCure.
AtriCure has a portfolio of products that include radio frequency and cryo ablation devices that are used during cardiac surgery. AtriCure’s cryoICE cryo ablation system has been indicated to freeze target tissue for the treatment of cardiac arrhythmias. The recently expanded indication for the cryoICE probe “for use in blocking pain by temporarily ablating peripheral nerves” provides surgeons with an additional option to treat post-thoracotomy pain.
“The pain management options available today are not optimal,” said Andrea Trescot, M.D., past president of the American Society of Interventional Pain Physicians. “Cryoanalgesia has been studied for many years, and has been shown to successfully block pain with no long term neural effects.”
Currently, surgeons use epidurals, intercostal nerve blocks and prescription narcotics for pain management. Studies have suggested that cryoanalgesia is a useful method for both short- and long-term relief from pain related to thoracotomy access. It is estimated that more than 25,000 cardiac and thoracic surgeries are performed in the United States every year using a thoracotomy approach.
“I have used cryoanalgesia as an adjunct to conventional pain relief techniques in nearly 75 cases of mitral valve surgeries via mini-thoracotomies,” said Francis Shannon, M.D., cardiothoracic surgeon with the Beaumont Health System in Michigan. “I have been very impressed with the reduction in respiratory complications after surgery as well as narcotic requirements for chest pain.”
Based in West Chester, Ohio, AtriCure develops atrial fibrillation (Afib) technology designed to reduce the economic and social burden of atrial fibrillation. AtriCure’s Synergy Ablation System is touted to be the only surgical device approved for the treatment of persistent and longstanding persistent forms of Afib in patients undergoing certain open concomitant procedures. Afib affects more than 33 million people worldwide.
