The MULTI-ARRAY ABLATION CATHETER (MAAC) is a multi-electrode catheter designed to map and ablate complex fractionated atrial electrograms (CFAE) in the left atrial body.
Three-Dimensional Anatomic Catheter Design
Nitinol framework conforms to the variability of the left atrium to maximize electrode-tissue contact
Symmetric, bi-directional steering allows the user to locate and ablate CFAEs in all areas of the left atrium
Multi-Electrode Array
Map and ablate through any or all electrodes as required
Unidirectional catheter deployment ensures that all thermocouples are located at the electrode tissue interface
Accurate temperature measurement aids delivery of energy levels appropriate to the required lesion depth and fill
Pure platinum, finned electrodes enhance electrode cooling in areas of low flow in the left atrial body
