Develops and sells, where authorized, the vCLAS catheter system for ventricular-tachycardia ablation, built on Ultra-Low Temperature Ablation technology. Its business combines clinical and regulatory development with limited overseas commercialization, while U.S. use remains investigational and its portfolio is concentrated in the vCLAS/ULTA platform family.
Develops catheter-based Ultra-Low Temperature Ablation technology for treating cardiac arrhythmias, with vCLAS as its principal platform for ventricular tachycardia. The system is designed to create deep, durable endocardial lesions without irrigation; sales are limited to Europe and selected authorized markets, while it remains investigational in the United States.
Combines device engineering, preclinical work, clinical studies, regulatory submissions, and selective commercialization. Its current portfolio and main pipeline concentrate in the vCLAS/ULTA family, including the FULCRUM-VT pivotal program, a next-generation catheter, and pulsed-field cryoablation technology.
Depends on U.S. commercial expansion on PMA review, clinical evidence, manufacturing readiness, and physician and hospital adoption against established electrophysiology systems.
