Diamond Temp
Alert Indications, Safety, and Warnings

Overview

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

Details

  • 7.5 Fr, open-irrigated catheter

  • 4.1 mm catheter tip segment

  • 6 externally placed temperature-sensing thermocouples,

  • Dual composite tip electrode

  • 2 ring electrodes

  • 6 irrigation ports

Includes customized offerings:

  • Small and large curve configurations

  • Unidirectional and bidirectional models
