The Boston Scientific BLAZER DX-20 Bidirectional Duodecapolar Electrophysiology Mapping Catheter (REF M00420SL555) is a steerable diagnostic catheter intended for intracardiac electrogram recording and programmed electrical stimulation during electrophysiology (EP) studies. Its 20-electrode (duodecapolar) configuration supports multi-site mapping along complex anatomical structures, while bidirectional deflection assists navigation and stable tissue contact during diagnostic procedures.
Key Features
Duodecapolar (20-electrode) array for high-resolution multi-site intracardiac mapping
Bidirectional tip deflection for enhanced maneuverability and reach
Steerable shaft engineered for predictable torque response and catheter control
Platinum electrodes designed for clear signal acquisition and pacing
Designed for compatibility with standard EP recording and stimulation systems
Single-use, sterile packaging to support procedural workflow
Clinical Applications
Diagnostic electrophysiology studies of supraventricular and ventricular arrhythmias
Mapping of the cavotricuspid isthmus, coronary sinus, and right atrial structures
Recording of intracardiac electrograms during ablation procedures
Programmed electrical stimulation and pacing protocols
Activation and sequence mapping in complex cardiac anatomy
