The Johnson & Johnson WEBSTER Hexapolar Fixed Catheter (REF 37D03R) is a single-use diagnostic electrophysiology catheter designed for intracardiac mapping, signal recording and programmed electrical stimulation. The fixed-curve shaft and six-electrode (hexapolar) distal array support stable positioning in standard EP study locations such as the high right atrium, His bundle region, coronary sinus or right ventricle.
Key Features
Hexapolar (6-electrode) distal configuration for multi-site recording and pacing
Fixed-curve shaft geometry for predictable placement and torque response
Platinum electrodes engineered for high-fidelity intracardiac electrogram acquisition
Braided shaft construction supporting 1:1 torque transmission
Standard electrical connector compatible with common EP recording and stimulation systems
Sterile, single-patient-use configuration
Electrode spacing as indicated in the product reference (2-5-2-5-2 mm pattern as labeled)
Clinical Applications
Diagnostic electrophysiology studies for evaluation of supraventricular and ventricular arrhythmias
Recording of intracardiac electrograms from the high right atrium, His bundle and right ventricle
Coronary sinus signal acquisition during mapping procedures
Programmed electrical stimulation and pacing maneuvers
Adjunctive use during catheter ablation workflows where a stable diagnostic reference is required
