The POLARx™ Cryoablation System


Paroxysmal Atrial Fibrillation Treatment Using the Precision of POLARx

It is known that paroxysmal atrial fibrillation therapy by cryoablation is fast and efficient. Therefore, we have expanded our EP portfolio with a unique procedure. The new POLARx Cryoablation System takes what you know—and trust—about cardiac ablation using cryo therapy and leaves the limitations behind. POLARx is a cryoablation balloon catheter, which uses innovative technology to create a more direct path to PVI. For a trustworthy solution of handling cardiac ablation of afib, Boston Scientific built the system from the ground up to give physicians the control they need to generate more predictable outcomes during afib treatment.

POLARx FIT is challenging the norm.

POLARx is the only Cryoablation System that offers 2 balloon sizes in 1 catheter

giving EPs more flexibility to effectively occlude variable PV anatomies at the touch of a button.
