The LASSO Duo-Decapolar Catheter (REF D7L2015CT) by Johnson & Johnson (Biosense Webster) is a circular diagnostic electrophysiology mapping catheter engineered to acquire high-fidelity electrograms around the pulmonary vein ostia and other tubular structures within the heart. Its preformed loop tip provides stable circumferential contact, supporting precise signal acquisition during atrial fibrillation ablation procedures.
Key Features
Duo-decapolar electrode configuration delivering 20 mapping electrodes for dense circumferential signal acquisition.
Preformed circular loop tip designed for stable apposition at pulmonary vein ostia.
European diameter curve tip configuration for compatibility with standard transseptal workflows.
Defined electrode spacing intended to support high-resolution local electrogram recording.
Compatible with standard EP recording systems via proximal connector.
Single-use, sterile device intended for diagnostic mapping use.
Clinical Applications
Circumferential mapping of the pulmonary vein ostia during atrial fibrillation ablation.
Confirmation of pulmonary vein isolation (entrance and exit block assessment).
Mapping of tubular cardiac structures where a circular multi-electrode array is indicated.
Adjunctive diagnostic mapping during complex atrial arrhythmia procedures.
