ENZERRO is an advanced microcatheter system that enhances safety in embolization procedures by detecting reflux, the unintended backward flow of embolic particles into surrounding organs. A miniature sensor continuously monitors pressure and flow, triggering real-time alerts or automatic shutoff if dangerous patterns emerge. AI-powered recognition adapts to patient-specific flow profiles, distinguishing risk from routine variation. Seamlessly integrating into existing workflows, ENZERRO not only improves clinical safety but also supports training, with potential applications across interventional radiology
