TACTICATH™ QUARTZ ABLATION CATHETER FEATURES AND REQUIREMENT
The main features of this unique ablation catheter include:
- Force sensor at the distal catheter tip
- Fiber optic technology for optimal stability during contact force measurement
- 65 or 75 mm deflectable curve
- Requires TactiSys™ Quartz hardware system and accessories
- Compatibility with steerable sheaths (such as the Agilis™ NxT introducer), resulting in increased contact force6
UNIQUE ADVANTAGES OF THE TACTICATH™ QUARTZ ABLATION CATHETER AND THE TACTISYS™ QUARTZ SYSTEM
Designed for seamless integration, the TactiSys Quartz system is a plug-and-play system—eliminating the need for thermal calibrations. It also offers:
- High-precision contact force measurements with 1 g resolution
- Real-time feedback: fast 50 Hz (20 ms) sample rate
- 2-5-2 electrode spacing for standard electrogram recordings
- Minimal influence of temperature for stable contact force measurement
- No impact on the force measurement accuracy from nearby ferrous materials (braiding of sheath, nearby circular mapping catheters)
- The FTI™ index, a proprietary index calculating force over time, has been clinically validated and is incorporated into the TactiCath Quartz contact force sensing ablation catheter labeling3-5
- The LSI (Lesion Index) is a proprietary index combining contact force, radiofrequency (RF) application duration and RF current**
- Full integration with the EnSite™ Precision™ cardiac mapping system via the EnSite™ contact force module
