The Latest Generation cryoICE Cryoablation Probe Providing the Flexibility Desired and Consistency Needed
The cryoFORM probe builds off of AtriCure’s core strengths in cryoablation technology, leveraging such features as thermal capacity to remove heat and Active Defrost, which allows the probe to be safely and quickly detach while maintaining the tissue’s frozen state.
cryoFORM Quick Facts:
- Increased probe flexibility to adapt to a variety of surgical ablation procedures
- Intended to address the trend towards more minimally invasive techniques by allowing surgeons to easily shape and position the probe using endoscopic instruments
- Corrugated 10 cm malleable stainless steel probe
- Retractable handle exposes active probe length
- Flexible tube set allows for tight bending radius
- Ergonomic handle accommodates to multiple hand positions
- Active Defrost feature allows probe to be removed from surface keeping tissue in frozen state
Why cryoICE with Nitrous Oxide (N2O)?
Removes Heat Faster1 / Stays Frozen Longer
1 / Fast Performance
cryoICE is quick to achieve lethal temperatures and maintains that temperature consistently along the probe length. The probe / tissue surface temperature is actively measured through a thermocouple feature.
2 / Superior Science
cryoICE has superior work capacity. Nitrous Oxide (N2O) has a higher heat absorption capacity than Argon.2
3 / Innovative Ergonomics
cryoICE has a retractable handle to expose the active probe length. In addition, its flexible tube set allows for a tight bending radius, and the ergonomic handle can adjust to multiple hand positions.
4 / Active Defrost
Active Defrost allows the probe to be quickly detached maintaining the tissue’s frozen state.
"Slow thawing of the frozen tissue is a prime destructive factor and is a more important mechanism of cell death in cryosurgery than is rapid cooling. The rate of thawing should be as slow as practical, and is best done by allowing the tissues to thaw with no assistance by heating. Rapid thawing increases the chance of cell survival, which has long been known in the treatment of frostbite."3
The cryoICE cryoFORM cryoablation probe is indicated for use in the cryosurgical treatment of cardiac arrhythmias by freezing target tissues, creating an inflammatory response (cryonecrosis) that blocks the electrical conduction pathway.
