DiamondTemp™ Ablation System
for Real-time, Temperature-controlled Ablation
As the only open-irrigated RF catheter with industrial diamonds to optimize power based on tissue surface temperature, the DiamondTemp ablation system (DTA) with RealTemp is safe and effective, and has demonstrated procedural efficiencies compared to contact force-sensing RF.1Download Brochure
The 8.0 Fr ablation catheter includes industrial diamonds, enabling rapid cooling due to their high thermal diffusivity property. The catheter tip is comprised of platinum-iridium and diamond components. A network of chemical vapor deposit (CVD) industrial diamonds acts as heat-shunting material.
Exclusive diamond shunt network enables rapid catheter tip cooling and a low-flow irrigation rate of 8 ml/min.2
Temperature provides direct feedback on lesion creation. Irreversible tissue damage is created at temperatures > 50° C.5
A high-resolution electrode (HRE) at the catheter tip allows for the recording of highly localized signals at the center of ablation with minimal far-field artifact.2
The 8.0 Fr open-irrigated catheter features a 4.1 mm tip segment consisting of six externally placed temperature-sensing thermocouples, a dual composite tip electrode, two ring electrodes, and six irrigation ports.
Includes customized offerings:
1. 2.0 mm
2. 3.5 mm
3. 4.1 mm
4. 3x Distal Thermocouples
5. 6x Irrigation Ports
