The Terumo Neuro FRED System 3.5 (REF FRED3536) is a dual-layer flow diverter designed for the endovascular treatment of intracranial aneurysms. The device combines an outer low-porosity stent with an inner high-porosity braid in a single delivery system, intended to redirect blood flow away from the aneurysm sac while supporting parent artery reconstruction.

Key Features
Dual-layer braided design integrating flow-diverting inner mesh and outer stent scaffold.
Self-expanding nitinol construction with tantalum radiopaque markers for fluoroscopic visibility.
Pre-loaded on a single delivery wire for controlled deployment and partial resheathing prior to detachment.
Nominal labeled diameter 3.5 mm; working length and vessel sizing per manufacturer instructions for use.
Designed for navigation through standard neurovascular microcatheters compatible with the FRED System (refer to current IFU for compatibility).

Clinical Applications
Endovascular flow diversion of intracranial aneurysms in selected parent arteries.
Reconstruction of the parent vessel in wide-neck, large, or complex aneurysm morphologies.
Use within the labeled vessel diameter and indication range as defined by the manufacturer's instructions for use and applicable regional regulatory clearance.
