The Boston Scientific BLAZER DX-20 Bidirectional Duodecapolar Electrophysiology Diagnostic Mapping Catheter (REF M00420M5405) is a steerable diagnostic catheter designed for intracardiac recording, signal acquisition, and programmed electrical stimulation during electrophysiology (EP) studies. Its 20-electrode (duodecapolar) array and bidirectional deflection are intended to support multi-site mapping along complex anatomical structures during diagnostic EP procedures.
Key Features
Bidirectional tip deflection for navigation and curve management within cardiac chambers.
Duodecapolar configuration with 20 platinum electrodes for high-resolution intracardiac signal acquisition.
Designed to deliver programmed electrical stimulation as part of diagnostic EP workflows.
Braided shaft construction intended to support torque response and shape retention.
Color-coded handle and deflection mechanism designed for intuitive single-hand operation.
Single-use, sterile diagnostic device for use in the EP lab.
Clinical Applications
Intracardiac electrogram recording during diagnostic electrophysiology studies.
Multi-site mapping along linear anatomical structures such as the crista terminalis, tricuspid annulus, or coronary sinus region.
Programmed electrical stimulation to support arrhythmia characterization.
Use as a reference or mapping catheter alongside ablation procedures performed with separate compatible devices.
