Alert Indications, Safety, and Warnings

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.

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
