Rapid mapping, improved accuracy, and enhanced map-point density
The OCTARAY™ Mapping Catheter and CARTO PRIME® Module provide an efficient solution with rapid mapping, improved accuracy, and enhanced map-point density to identify triggers for guiding ablation of complex arrhythmias.
TRUEref™ Technology
OCTARAY™ features a unipolar reference electrode located at the base of the catheter, known as TRUEref™ Technology that can be used as an alternative unipolar mapping reference.
This may limit the impact of far field signals and ambient lab noise on signal quality.
