POLARx (cryoablation system)

2023: Product Announcement

On August 8, 2023, Boston Scientific announced the POLARx cryoablation system. The solution is intended for the treatment of arrhythmia by freezing.

The new system focuses on patients with paroxysmal atrial fibrillation (atrial fibrillation). Such people usually complain of bouts of non-rhythmic heartbeat. They can occur against a background of physical or emotional exertion, as well as at rest, in the evening or at night, after eating or drinking alcohol.

An effective method of treating said ailment is pulmonary vein isolation. For this, cryoablation is used - a minimally invasive procedure, during which the balloon catheter delivers cryotherapy to the pulmonary vein. This causes the problem tissue to freeze and form scarring that blocks irregular electrical signals. The system is said to eliminate known limitations by rethinking existing approaches for cryoablation. Surgeons can adjust the catheter according to the patient's individual anatomy during the ablation procedure. Device also allows to create lesions in optimal orientation, which increases therapy efficiency.

The new POLARx cryoablation system, and specifically the expandable cryoballon catheter, is an advanced development to effectively treat atrial fibrillation because it allows surgeons to better tailor care for individual patients without sacrificing safety or the resulting outcome, said Wilber Su, MD.

Clinical trial data confirmed the safety and efficacy of the POLARx cryoablation system in the treatment of 385 patients with paroxysmal atrial fibrillation. The complex is approved for use in the USA, Europe, Japan, Canada and countries of the Asia-Pacific region.^[1]
