The Boston Scientific BLAZER DX-20 Bidirectional Duodecapolar Electrophysiology Diagnostic Mapping Catheter (REF M00420SL2102) is a steerable multi-electrode diagnostic catheter engineered to support intracardiac signal acquisition, pacing and mapping during electrophysiology (EP) studies. Featuring 20 electrodes (duodecapolar configuration) and bidirectional tip deflection, the BLAZER DX-20 is intended to help clinicians navigate complex cardiac anatomy and record electrical activity from multiple sites along a single catheter shaft.

Key Features
- Duodecapolar electrode array (20 electrodes) for multi-site intracardiac recording and stimulation along a single shaft.
- Bidirectional distal deflection for enhanced steerability and access to challenging anatomies.
- Atraumatic distal tip designed to facilitate safe navigation within the cardiac chambers.
- Torque-responsive shaft engineered for predictable handling and 1:1 tip control.
- Standard EP connector compatible with commonly used recording and stimulation systems.
- Sterile, single-use device supplied in protective packaging.
- Manufacturer reference: REF M00420SL2102.

Clinical Applications
- Diagnostic electrophysiology studies requiring multi-site intracardiac electrogram recording.
- Programmed electrical stimulation and pacing protocols during EP procedures.
- Activation and sequence mapping along linear cardiac structures (e.g., coronary sinus and other endocardial sites) where clinically indicated.
- Use as a reference catheter during ablation and complex EP workflows, per institutional protocols.
- Intended for use by trained electrophysiologists in appropriately equipped EP laboratories.
