Freezor Cardiac Cryoablation Catheters

Cardiac Ablation for Atrial Fibrillation


The Freezor™  family of cardiac cryoablation catheters are flexible, single-use, minimally invasive devices designed to ablate cardiac tissue.

Freezor catheters, used in conjunction with the CryoConsole, are the only focal catheters that utilize the cryo energy source, with ablation indications ranging from atrioventricular nodal reentry tachycardia (AVNRT) to atrial arrhythmias.  


Freezor and Freezor Xtra Cardiac Cryoablation Catheters are designed to create focal lesions to treat AVNRT.

Freezor and Freezor Xtra

The Freezor Xtra catheter is also intended for minimally invasive cardiac surgery procedures, including surgical treatment of cardiac arrhythmias. The Freezor Xtra catheter freezes the target tissue and blocks the electrical conduction by creating scar tissue.

Freezor MAX Cardiac Cryoablation Catheter is an adjunctive device used in the endocardial treatment of paroxysmal and persistent atrial fibrillation (episode duration less than 6 months) to complete pulmonary vein isolation (PVI) if needed. It may also be used for:

  • Gap cryoablation to complete electrical isolation of the pulmonary veins
  • Cryoablation of focal trigger sites
  • Creation of ablation line between the inferior vena cava and the tricuspid valve
