Cryoablation System Overview Cardiac Ablation for Atrial Fibrillation


ARCTIC FRONT ADVANCE CARDIAC CRYOABLATION CATHETER SYSTEM

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

The Arctic Front Advance Cardiac Cryoablation Catheter is indicated for the treatment of drug refractory recurrent symptomatic paroxysmal atrial fibrillation. The cryoballoon has been used to treat over a quarter of a million patients in more than 50 countries worldwide.1 Findings from a large clinical trial found that the cryoballoon was a safe and effective treatment after drug failure.2

THE SYSTEM AT A GLANCE

The Arctic Front Advance Cardiac Cryoablation Catheter uses cryo energy to isolate the pulmonary vein.

The FlexCath Advance Steerable Sheath helps deliver and position the Arctic Front Advance Cryoballoon in the left atrium.

FlexCath Advance Steerable Sheath

The CryoConsole houses the coolant, electrical and mechanical components that run the catheters during a cryoablation procedure.

CryoConsole

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

Achieve and Achieve Advance Mapping Catheters

The Freezor MAX Cardiac Cryoablation Catheter is a single-point catheter used to perform touch-up cryoablation to complete electrical isolation of the pulmonary veins as needed.

HOW THE ARCTIC FRONT ADVANCE SYSTEM WORKS

Designed with PVI in mind, the Arctic Front Advance Cryoballoon is an anatomical approach for PVI, creating long contiguous circumferential lesions surrounding the pulmonary vein.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.

How Arctic Front Advance Cryoballoon Works


Access Targeted Vein

Access Targeted Vein
  • The Arctic Front Advance Cryoballoon is inserted over a guide wire through the FlexCath Advance Steerable Sheath to the left atrium.
  • The Achieve Advance Mapping Catheter is then inserted into the target vein.

Inflate and Position

Inflate and Position
  • The cryoballoon 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.

Ablate and 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.
