Product Features

The TactiCath™ Contact Force Ablation Catheter, Sensor Enabled™ offers the following features:*

  • Force sensor at the distal catheter tip
  • Fiber optic technology for optimal stability during contact force measurement
  • D, F, and J uni-directional and D-D, D-F, F-F, F-J, and J-J bi-directional deflectable curves
  • 2-2-2 electrode spacing for standard electrogram recordings
  • Compatibility with steerable sheaths (such as the Agilis™ NxT introducer), resulting in increased contact force1
  • Minimal influence of temperature for stable contact force measurement

*Requires TactiSys™ Quartz hardware system and accessories

Unique advantages of the TactiCath Contact Force Ablation Catheter, Sensor Enabled and the TactyiSys Quartz System

Designed for seamless integration, the TactiSys Quartz system is a plug-and-play system that eliminates the need for thermal calibrations.

TactiSys also offers:

  • High-precision contact force measurements with 1 g resolution
  • Real-time feedback: Fast 50 Hz (20 ms) sample rate
  • No impact on the force measurement accuracy from nearby ferrous materials (braiding of sheath, nearby circular mapping catheters)

Force Time Integral (FTI Index)

The FTI™ index is a clinically validated proprietary index calculating force over time. FTI index is incorporated into the TactiCath Quartz contact force sensing ablation catheter labeling.2

Line graph showing force time interval by ablation duration. FTI equals contact force times time.

Lesion Index (LSI)

The LSI (Lesion Index) is a proprietary index combining contact force, radiofrequency (RF) application duration and RF current. This parameter was designed to model both the resistive heating and thermal conduction stages of lesion formation.
