cryoICE Cryoablation Probes
with Nitrous Oxide (N20)
Removes Heat Faster1 / Stays Frozen Longer
Product Codes: CRYO2, CRYO3
The cryoICE cryoablation probes are built off AtriCure’s core strengths in cryoablation technology, leveraging such important features as thermal capacity to remove heat and active defrost, which allows the probe to be safely and quickly detached while maintaining the tissue’s frozen state.
Why the cryoICE Cryoablation Probe?
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 while 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
