Cardioblate Cryoflex Argon-powered Ablation
The Cardioblate® CryoFlex™ Surgical Ablation System provides the capability of creating deep, extensive lesions to treat cardiac arrhythmias through sternotomy and minimally invasive approaches. Compared with radiofrequency, cryoablation provides added safety around vulnerable tissue structures.1,2
- Probe tips 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
The Argon Gas Advantage
Argon gas is the coldest ablation source commercially available for the surgical treatment of cardiac arrhythmias. The CryoFlex probe reaches temperatures of approximately -150°C in test freezes.3 Compared with dry radiofrequency ablation sources, cryoablation provides the following advantages:1
- Well-delineated, discrete lesions
- Preservation of tissue ultrastructure (including endothelial cell layer)
- Greater fibrotic tissue ingrowth
- Cardioblate® CryoFlex™ Surgical Ablation Probes
- Cardioblate® CryoFlex™ 10-S Surgical Ablation Probe
- Cardioblate® CryoFlex™ Clamp and Surgical Ablation Probe
- Cardioblate® CryoFlex™ Surgical Ablation Console
