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
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.
