These are single-use catheters designed to ablate cardiac tissue by creating focal lesions. Used in conjunction with the CryoConsole™.Dowload brochure
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 atrial ventricular nodal reentrant tachycardia (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.
* Indicated for patients over two years of age.
The Freezor and Freezor Xtra catheters are the only FDA-approved ablation catheters for the treatment of AVNRT in both pediatric* and adult patients. Patient outcomes include:
* Indicated for patients over two years of age.
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:
