Pioneering Contact Force Technology: TactiCath™ Quartz Ablation Catheter

The TactiCath™ Quartz ablation catheter gives you contact for CF measuring capability and is the first catheter to provide you with recommendations for CF sensing during PVI procedures.9 Measuring CF between the catheter tip and the tissue surface can help guide you during your mapping and ablation procedures for certain treatments of atrial fibrillation.

In order to provide you with the best technology, we rely on clinical evidence to design and support our products. Several publications and abstracts support the accuracy, safety and effectiveness of the device globally.5,6,10,11

Novel Design, Optimal Handling: FlexAbility™ Ablation Catheters

Created using physician feedback from concept to completion, the FlexAbility™ ablation catheters are intended to yield safe, effective outcomes for your patients in the treatment of typical atrial flutter.2-4 The design is also meant to provide you with the consistent performance and enhancements*,12 for comfort that you need during long procedures.*,12 

Designed for optimal torque13 and planarity*,12, the FlexAbility ablation catheters have been shown to:

  • Have directed irrigation that optimizes cooling with flow directed to the tissue3
  • Result in potentially lower adverse events4 
  • Provide effective lesion formation3,4 
  • Result in no charring and coagulum due to flexible tip2
  • Have 1 mm distal tip spacing that optimizes signal quality14
  • Demonstrate maneuverability and durability for effectiveness12

Clinical Evidence

Data from several studies such as TOCCATA, EFFICAS I and EFFICAS II show that CF sensing is not only safe for use in PVI but is also associated with lower rates of gap and atrial fibrillation (AF) recurrence.5,11,15 The TOCCASTAR investigational device exemption (IDE) study provided evidence supporting the safety and effectiveness of the TactiCath™ ablation catheter for the treatment of proxysmal AF.16

Economic Evidence

Since the high cost of treating cardiac arrhythmias creates an economic burden on the health care system, we design lab technologies to help you improve procedural costs. We offer a suite of comprehensive solutions designed to streamline lab procedures and reduce clinical overhead. The reliability and flexibility that our advanced ablation tools place in your hands can help you work more efficiently, keeping hospital costs to a minimum.
