Cryoablation System Overview Cardiac Ablation for Atrial Fibrillation


The Arctic Front Cardiac Cryoablation Catheter Family System* includes the Arctic Front Advance™ Cryoballoon, which is used in conjunction with the Nitron CryoConsole™, the FlexCath Advance™ Steerable Sheath, and the Achieve™ and Achieve Advance™ Mapping Catheters.

The Arctic Front Cardiac Cryoablation Catheter Family is indicated for the treatment of  atrial fibrillation. The cryoballoon has been used to treat over half a million patients in more than 60 countries worldwide.1

Findings from a large clinical trial found that the cryoballoon was a safe and effective treatment.2

The Arctic Front Cardiac Cryoablation Catheter Family uses cryo energy to isolate the pulmonary veins.

The Achieve and Achieve Advance Mapping Catheters are diagnostic catheters used to measure electrical signals before, during and after ablation.

HOW the Arctic Front Cardiac Cryoablation Catheter Family SYSTEM WORKS

Designed with PVI in mind, the Arctic Front Cardiac Cryoablation Catheter Family is an anatomical approach for PVI, creating long contiguous circumferential lesions surrounding the pulmonary veins.3 Providing physicians with a straightforward approach for PVI, the cryoballoon isolates each pulmonary vein with minimal energy applications, delivering consistent and predictable results.4

Watch the video below to see how the Arctic Front Advance Cryoballoon works.

Access Targeted Vein

Access Targeted Vein
  • The Achieve Family Mapping Catheter is inserted into the target pulmonary vein.
  • The Arctic Front Cardiac Cryoablation Catheter is then advanced out of the Flexcath Advance Steerable Sheath into the left atrium.

Inflate and Position

Inflate and Position
  • The Arctic Front Cardiac Cryoablation Catheter is inflated in the atrium before being advanced toward the wired vein.
  • The balloon is then positioned at the antrum of the pulmonary vein.

Complete Occlusion

Complete Occlusion
  • Contrast dye is injected through the guide-wire lumen to assess vein occlusion via fluoroscopy.

Assess PVI

Ablate and Assess PVI
  • The cryoballoon ablates where the balloon is in contact with the tissue, using pressurized liquid nitrous oxide (N2O) delivered from a tank in the CryoConsole.
  • The cryoballoon’s anatomical shape and large surface area creates circumferential lesions with minimal energy applications.
  • The Achieve Advance catheter is then used to confirm pulmonary vein isolation.
