Radiofrequency (RF) ablation
No need to choose between technology advancement and a seamless experience. With you and your patient experiences in mind, we are committed to maintaining an integrated design that complements your existing workflows.
As ablation energy sources evolve, the fully-integrated CARTO™ 3 System is the cornerstone of catheter ablation to enable accurate, real-time catheter visualization and empower you to make optimal, patient-tailored treatment decisions.


Our ‘Integrated by Design’ approach goes far beyond a portfolio
Our suite of products have been designed and engineered to work seamlessly together, ensuring optimal functionality, and compatibility.
This integration goes beyond the simple coexistence of different instruments – it is a conscious effort to create a synergistic system that enhances overall performance and outcomes.


A smarter ablation in a fraction of the time*1
QDOT MICRO™ Catheter
Advanced ablation: With QMODE+™ Module temperature control, the generator delivers the high RF energy at the set power for the set short duration or until the target temperature is reached.
Optimized irrigation: Irrigation rate varies automatically for optimized power delivery, ensuring the tip is within the allowed target temperature range.**2
Improved temperature monitoring: Temperature sensitivity that enables temperature control on an irrigated catheter with the addition of 6 thermocouples embedded into the tip.**3
Higher signal resolution: QDOT MICRO™ Catheter includes 3 microelectrodes providing high resolution electrograms and discrete local signals.**


Uniform cooling for optimal efficiency
THERMOCOOL SMARTTOUCH™ SF Catheter
THERMOCOOL SMARTTOUCH™ SF Catheter – the most commonly used catheter in the world today. The porous tip of the catheter paired with contact force technology is designed to optimize efficiency. The THERMOCOOL SMARTTOUCH™ SF Catheter provides uniform cooling at half the flow rate of earlier generation irrigated catheters, easing the fluid management process.
The THERMOCOOL SMARTTOUCH™ SF Bi-Directional Navigation Catheter is a multi-electrode luminal catheter with a deflectable tip designed to facilitate electrophysiological mapping of the heart and to transmit radiofrequency (RF) energy to the catheter tip electrode for ablation purposes.
The catheter shaft measures 7.5 F with 8 F ring electrodes. For ablation, the catheter is used in conjunction with a compatible RF generator and a dispersive pad (indifferent electrode). The catheter has force-sensing technology that provides a real-time measurement of contact force between the catheter tip and the heart wall.
