The Johnson & Johnson WEBSTER Hexapolar Fixed Diagnostic Catheter (REF 37D55R) is a steerable-tip class diagnostic electrophysiology catheter designed for intracardiac signal acquisition and programmed electrical stimulation. Featuring a fixed curve configuration with six platinum electrodes, it is intended to support reliable mapping and pacing during diagnostic EP procedures in the cardiac chambers.
Key Features
Six-electrode (hexapolar) distal array for multi-site intracardiac electrogram recording
Fixed curve shaft geometry for consistent placement and stable contact
Platinum electrodes engineered for high-fidelity signal quality
Braided shaft construction supporting torque response and pushability
Standard EP recording system connector compatibility
Single-use, sterile packaging
Electrode spacing configuration referenced in the product designation (2-5-2 mm pattern); confirm exact spacing against the official IFU prior to use
Clinical Applications
Diagnostic electrophysiology studies requiring multi-electrode intracardiac recording
Programmed electrical stimulation and pacing maneuvers
Activation and conduction interval measurement
Reference catheter use in arrhythmia evaluation workflows
Adjunctive use during ablation procedures where a fixed diagnostic catheter is indicated
