FRED Junior System 2.5 | REF FREDJR2508
Terumo Neuro FRED Junior System 2.5 (REF FREDJR2508) is a low-profile dual-layer flow diverter designed for the endovascular treatment of intracranial aneurysms in smaller parent vessels.

The Terumo Neuro FRED System 4.0 (REF FRED4026) is a flow diverting stent designed for the endovascular treatment of intracranial aneurysms. The FRED (Flow Re-Direction Endoluminal Device) platform is built around a proprietary dual-layer braided nitinol mesh that combines an inner low-porosity flow-diverting layer with an outer higher-porosity stent layer, intended to support consistent vessel wall apposition and aneurysm flow disruption.
