The MULTI-ARRAY SEPTAL CATHETER (MASC) is a multi-electrode catheter designed to map and ablate complex fractionated atrial electrograms (CFAE) along the left atrial septum.
Three-Dimensional Anatomic Catheter Design
Nitinol framework conforms to the variability of the left atrial septum
Wide footprint disperses contact pressure for safer manipulation and provides stable placement
Easily covers the entire septum with a simple approach for mapping and ablation
Multi-Electrode Array
Map and ablate simultaneously through all electrodes or selectively as needed
Electrode placement on the array simplifies septal access and ensures thermocouple localization at the endocardial surface for more accurate temperature measurement
Accurate temperature measurement aids in delivering energy levels appropriate to the required lesion depth and fill
Pure platinum, finned electrodes enhance passive electrode cooling in the low flow area of the septum
