CryoFlex™ Surgical Ablation Probe

CryoFlex™ Surgical Ablation Probe

+ Enlarge

The CryoFlex Surgical Ablation Probe provides the capability of creating deep, extensive lesions to treat cardiac arrhythmias through a single, right-sided thoracotomy. This probe uses Argon gas cryoablation to provide additional safety around vulnerable tissue structures compared to ordinary dry radiofrequency.1

  • Probe tip achieves temperatures of approximately -150° C in test freezes2
  • Probe tip can be reshaped by hand to achieve good tissue apposition in varying surgical situations and approaches
  • A single probe can be used for all procedures
  • Can create deep, reproducible lesions

Products are subject to availability in each geography.
