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 FRED X Flow Diverter Stent from Terumo Neuro (REF XFRED3507, 3.5 mm x 13 mm) is a self-expanding, dual-layer braided intracranial flow diverter engineered to redirect blood flow away from the aneurysm sac while supporting parent artery reconstruction. The FRED X configuration incorporates a surface modification intended to reduce material thrombogenicity compared to the uncoated FRED device.
Key Features
Dual-layer braided design combining an outer low-porosity mesh with an inner higher-porosity stent for flow diversion and wall apposition.
Surface modification technology applied to the device to support reduced thrombogenicity.
Three radiopaque tantalum helical strands and distal/proximal markers for fluoroscopic visualization.
Nominal labeled dimensions: 3.5 mm nominal diameter x 13 mm working length.
Designed for delivery through compatible microcatheters; consult manufacturer IFU for catheter and guidewire compatibility.
Resheathable and repositionable prior to final deployment, per manufacturer instructions.
Clinical Applications
Endovascular flow diversion for intracranial aneurysms in appropriately selected vasculature.
Reconstruction of the parent vessel across wide-necked, fusiform, or complex aneurysm morphologies.
Use within neurointerventional procedures performed by trained operators. Patient selection, indications, contraindications, and approved use must follow the current Instructions for Use and applicable regional regulatory labeling.
