DIAMONDTEMP™ ABLATION SYSTEM
Advanced Ablation Products for EP Procedures
The DiamondTemp™ Ablation Catheter is the only real-time, low-flow, open-irrigated, temperature-controlled RF catheter that creates safe and effective cardiac lesions via quick conduction of thermal energy enabled by industrial diamonds.Download Brochure
The DiamondTemp™ Ablation Catheter is the only real-time, low-flow, open-irrigated, temperature-controlled RF catheter that creates safe and effective cardiac lesions via quick conduction of thermal energy enabled by industrial diamonds.
The DiamondTemp™ Ablation System runs in temperature-control mode. The RF generator measures the six thermocouples every 20 milliseconds and modulates power in real time to maintain optimal tip-tissue temperature for durable lesion creation.2
The following biophysical markers indicate a transmural lesion has been created:
The catheter and the RF generator are engaged in a continuous biophysical feedback loop, enabling the generator to modulate power to deliver RF energy to achieve optimal therapeutic temperature in real time.
The 7.5 Fr ablation catheter tip includes advanced-grade 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) synthetic diamonds acts as heat-shunting material.
An exclusive diamond shunt network enables rapid catheter tip cooling and a low-flow irrigation rate of 8 ml/min.4
A high-resolution electrode (HRE) at the catheter tip allows for the recording of highly localised signals at the centre of ablation with minimal far-field artifact.7
The 7.5 Fr, open-irrigated catheter also features a 4.1 mm catheter tip segment consisting of 6 externally placed temperature-sensing thermocouples, dual composite tip electrode, 2 ring electrodes, and 6 irrigation ports.
Includes customised offerings:
1. 2.0 mm
