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 Cryoablation Balloon Catheter

One balloon, two sizes for more antral occlusion: the only cryoablation system that offers 2 balloon sizes in 1 catheter

The right fit for AF cryoablation

Elasticity of modern balloon material expands to 28mm or 31mm, providing 20% more surface area to occlude and treat variable anatomies

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.
