The FRED Junior System 2.5 from Terumo Neuro (REF FREDJR2513) is a low-profile flow diverter from the FRED (Flow Re-Direction Endoluminal Device) family, engineered for the endovascular treatment of intracranial aneurysms located in smaller-diameter parent arteries. It features a dual-layer braided design that combines an inner low-porosity mesh for flow diversion with an outer stent structure for vessel wall apposition and support.

Key Features
Dual-layer braided nitinol design integrating flow-diverting inner mesh with outer support stent.
Low-profile configuration intended for delivery through small-bore microcatheters in distal and small-vessel anatomy.
Radiopaque markers to facilitate fluoroscopic visualization during deployment.
Designed to allow resheathing and repositioning prior to final detachment, per the manufacturer's instructions for use.
Nominal expanded diameter of 2.5 mm to address smaller parent vessels.

Clinical Applications
Endovascular flow diversion treatment of intracranial aneurysms.
Use in smaller and more distal intracranial arteries where standard flow diverters may not be suitable.
Treatment planning for wide-necked, fusiform, or complex aneurysm morphologies as determined by the treating physician.
