Freezor® – Perfectly Suited to Peri-nodal Procedures

Freezor® is a flexible, single-use, minimally invasive CryoAblation catheter designed to create focal lesions to treat arrhythmias where procedural precision is of critical importance. Freezor® can create temperatures at its tip as low as -85ºC inside a beating heart. Approximately half of arrhythmia procedures performed around the world fall into the peri-nodal category, where precision and safety are critical. In approximately 1.3% to 4% of these procedures, when traditional heat-based RF ablation is used, the patient's AV node is damaged. As a result, the patient may require a pacemaker for the remainder of his or her life. Freezor® offers a site-testing capability – which involves a technique called CryoMapping – which is helpful for physicians to avoid unwanted electro-physiological effect on AV node conduction.

CryoMapping – a Unique Feature

CryoMapping temporarily chills conducting tissue in the target area, creating a transient electrical effect. This allows for precise site testing and confirmation prior to proceeding with definitive ablation.

CryoAdhesion occurs during CryoMapping, ensuring that the catheter tip remains at the target site for a seamless transition to CryoAblation. CryoAdhesion maintains the position of the catheter tip in the beating heart, as the tip firmly attaches to the endocardium upon freezing. The transition from CryoMapping to CryoAblation is made with a quick touch on the cryoconsole screen.

Pre-clinical studies have shown that Freezor® creates endocardial lesions with minimal tissue disruption and minimal risk of thrombus and stenosis.
