Medtronic’s Arctic Front Advance? cardiac cryoballoon has received both US FDA and CE Mark approvals. The Arctic Front Advance is indicated for use in treating paroxysmal atrial fibrillation (PAF), and is an improvement on the previous Arctic Front model. The device features the new EvenCool? Cryo Technology, which optimises the delivery of coolant inside the balloon. This causes a larger, more uniform cold surface that reduces the effort needed to isolate the pulmonary veins, the target of most AF ablation procedures.
