afreeze uses innovative, proven cryotechnology for generating the extremely low temperatures required to freeze tissue and scar the problematic areas. This technology is based on the Joule-Thomson effect, which describes the drop in temperature accompanying the sudden expansion of a fluid forced through a porous plug that is kept insulated throughout the process.

afreeze uses this effect in the coolloop® catheter to create circular lesions in the human atrium, isolating the atria to combat atrial fibrillation.

We are proud of the continuous development of our products and of holding numerous patents on our cryotechnology and catheters in both the US and in Europe.
