Measuring Contact Force Through White Light Interferometry
Using light interferometry, the TactiCath™ Quartz Catheter makes an interference analysis to compute both magnitude and orientation of contact force.
- A cylindrical titanium sensor that contains 3 gaps (cavities) spaced evenly around the sensor is welded to the tip of the ablation catheter.
- When a pressure is applied to the tip, the width of the gap changes based on the pressure.
- Fiber optics based on Fabry-Pérot interferometry are used to measure this gap.
Designed for seamless integration
The intuitive display of contact force data allows for enhanced workflow. The EnSite™ contact force module shows the CF data on the EnSite Precision™ cardiac mapping system providing a single integrated display.
The TactiCath Quartz ablation catheter is also compatible with the following St. Jude Medical™ products:
