TactiFlex Ablation Catheter, Sensor Enabled



Ablate Efficiently with Predictability and Confidence

The first and only contact force catheter with a flexible tip.

Designed for optimal safety and stability, confident lesion creation and procedural efficiency,the TactiFlex™ Ablation Catheter, Sensor Enabled™ elevates ablation procedures through:

  • proprietary tip design and full integration with the revolutionary EnSite™ X EP System
  • Superior tip stability2,* and excellent signal quality3 during ablation
  • Predictability with intuitive contact force arrow and deflection direction indicator available with the EnSite X EP System4

Perform High-Power Ablation** with Safety and Stability, Confidence and Efficiency

Designed for Optimal Safety and Stability

  • Experience superior stability with a unique, flexible, laser-cut tip - up to 2X greater stability than conventional 56-hole catheters2
  • Apply directed irrigation flow5 to the tip-tissue interface, effectively cooling tissue for safe transmural ablation
  • Lower irrigation rate*** while ablating up to 50W to reduce fluid loading

Confident Lesion Creation

  • Ablate with the proven performance of the Abbott contact force platform6
  • Optimize contact force measurement through fiber-optic technology
  • High resolution (1g) real-time (50Hz) force display with thermal compensation and no interference from other catheters

Procedural Efficiency1 from intuitive handling and usability with full EnSite X EP System integration

  • Reduce PVI ablation times by as much as 70%**** with high-power short-duration ablation7
  • Usability and predictability with intuitive contact force arrow and deflection direction indicator4
  • Monitor lesion creation with excellent electrogram signal quality even during RF3
