Overview
The only irrigated and temperature-controlled RF ablation system empowered by diamonds
DiamondTemp™ catheter merges synthetic diamonds for temperature-control with a split-tip electrode for high-resolution local electrograms, allowing a rapid and effective ablation with direct assessment of the lesion formation.
Control the temperature Optimise the power
Exclusive diamond shunt network enables rapid catheter tip cooling
Lower irrigation flow rate is required as minimal heat is retained at the catheter tip.
Low-flow irrigation with direct measurement of tissue temperature
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.
Precise ablation guidance with localized high resolution electrograms
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
