Features

Freezor™ and Freezor Xtra™ catheters

Restoring life’s rhythm. Big and small.

Freezor™ and Freezor™ Xtra cardiac cryoablation catheters freeze the target tissue and block the electrical conduction by creating scar tissue. The catheters are designed to create focal lesions to treat (AVNRT) for both adult and pediatric† patients.

The Freezor™ Xtra catheter is also intended for minimally invasive cardiac surgery procedures, including surgical treatment of cardiac arrhythmias.

Clinical evidence

Proven. Predictable.

Freezor™ catheters are the only FDA-approved ablation catheters for the treatment of AVNRT in both pediatric† and adult patients. Patient outcomes include:

  • 0% of reported AVNRT cases resulted in permanent AV block1–16
  • 89% quality of life improvement after cryoablation1–16
  • ≥ 95% acute procedural success from AVNRT1–16

Freezor™ MAX

Look no further.

The Freezor™ MAX cardiac cryoablation catheter is an adjunctive device used in the endocardial treatment of paroxysmal and persistent atrial fibrillation (episode duration less than six 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
