Features

The next generation of radiofrequency (RF) ablation

Exclusive diamond-enabled tip tooling

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.

  1. Distal diamond
  2. Center diamond
  3. Proximal diamond

Exclusive diamond shunt network enables rapid catheter tip cooling and a low-flow irrigation rate of 8 mL/min.2

  • Thermal energy transfer is 200 to 400 times faster with CVD diamond versus platinum-iridium.3,4
  • Extremely high thermal diffusivity allows quick conduction of thermal energy through the diamond shunt network, enabling a low-flow irrigation rate and electrogram (EGM) signal clarity.2
The DiamondTemp™ ablation catheter exclusive diamond shunt network enables rapid catheter tip cooling and low flow irrigation rate of 8 ml/minute.

Real-time temperature-sensing technology

Temperature provides direct feedback on lesion creation. Irreversible tissue damage is created at temperatures > 50 C.5

  • The DiamondTemp™ ablation catheter runs in temperature-control mode.
  • RealTemp™ drives thermocouple readings by the generator 50 times per second and automatically adjusts the power to the ablation set temperature.
  • A new study shows that through operation in temperature control mode, the level of applied contact force does not influence lesion size for durations between 5 to 15 seconds.6
The DiamondTemp™ ablation system includes real-time temperature sensing technology, precise location guidance, and diamond-enabled tip cooling as a differentiated design.

Precise location guidance with localized EGMS 

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

Conventional electrodes

Bipolar mapping/pacing

The conventional RF catheter is at the center of mapping and center of ablation.

DiamondTemp™ hi-res electrodes

Bipolar mapping/pacing

The DiamondTemp™ ablation system catheter has a high-resolution electrode at the catheter tip, allowing the ability to record highly localized signals at the center of ablation with minimal far-field artifact.
