Lower irrigation flow rate is required as minimal heat is retained at the catheter tip.
During the ablation process, the tissue surface temperature is measured in real-time, 50 times per second. Ablation power is automatically adjusted to match the ablation set temperature.
A 1.1 mm high-resolution electrode (HRE) at the tip allows for the recording of highly localized EGMs at the center of ablation with minimal far-field artifact2
Align the center of ablation with the center of mapping with a close bipolar catheter tip configuration

4.1 mm catheter tip segment
6 externally placed temperature-sensing thermocouples,
Dual composite tip electrode
2 ring electrodes
6 irrigation ports
Includes customized offerings:
Small and large curve configurations
