The WEBSTER Hexapolar Fixed Diagnostic Catheter (REF 37D33R) from Johnson & Johnson is an electrophysiology (EP) diagnostic catheter designed for intracardiac electrogram recording and programmed electrical stimulation during EP studies. The fixed-curve shaft and hexapolar electrode array support stable positioning and consistent signal acquisition in standard diagnostic locations.
Key Features
- Six platinum electrodes arranged in a hexapolar configuration for multi-site recording and pacing
- Fixed curve shaft for predictable, reproducible placement
- Braided shaft construction intended to support torque transmission and shape retention
- Standard EP connector compatible with conventional recording and stimulation systems (verify with your lab's interface cable)
- Electrode spacing and curve dimensions: Not specified in the located sources; refer to the official IFU for the 37D33R configuration
Clinical Applications
- Intracardiac electrogram recording during diagnostic EP studies
- Programmed electrical stimulation for arrhythmia evaluation
- Mapping of standard diagnostic sites such as the His bundle, right atrium, right ventricle, or coronary sinus, as determined by the operator
- Adjunct use during supraventricular and ventricular arrhythmia workups
