The Johnson & Johnson WEBSTER Hexapolar Fixed-Curve Diagnostic Catheter (REF 37D38R) is a six-electrode intracardiac electrophysiology catheter engineered for reliable signal acquisition and stimulation during diagnostic EP studies. Built on the established WEBSTER platform from Biosense Webster, it offers a preformed fixed curve to support consistent positioning within target chambers of the heart.
Key Features
Hexapolar (6-electrode) configuration for multi-site recording and pacing
Fixed-curve shaft geometry for predictable, reproducible placement
Electrode spacing pattern indicated as 2-5-2 / 2-5-2 mm (per product nomenclature; verify on IFU)
Compatible with standard EP recording and stimulation systems
Torque-responsive shaft for controlled navigation
Single-use, sterile packaging
Clinical Applications
Diagnostic intracardiac electrogram recording
Programmed electrical stimulation during EP studies
Mapping of supraventricular and ventricular arrhythmias
His bundle, coronary sinus, right atrial or right ventricular signal acquisition as directed by the operating physician
Adjunct use in ablation workflows where diagnostic mapping is required
