FRED Junior System 2.5 | REF FREDJR2513
Terumo Neuro FRED Junior System 2.5 (REF FREDJR2513) is a low-profile dual-layer flow diverter stent designed for the endovascular treatment of intracranial aneurysms in smaller parent vessels.

The FRED Junior System 2.5 from Terumo Neuro (REF FREDJR2508) is a dual-layer flow diverter engineered for the endovascular management of intracranial aneurysms located in distal and smaller-caliber cerebral vessels. Built on the established FRED platform, the Junior configuration extends flow diversion therapy to anatomies where conventional flow diverters may not be suitable, offering a low-profile delivery system compatible with smaller microcatheters.
Key Features
Dual-layer braided mesh design combining an outer low-porosity inner layer and an outer stent layer for flow diversion and vessel wall apposition.
Low-profile construction intended for distal intracranial navigation and smaller parent vessel diameters.
Radiopaque markers to support fluoroscopic visualization during deployment.
Designed for controlled deployment and potential resheathing prior to full detachment (refer to manufacturer IFU for specific resheathing limits).
Compatible with low-profile microcatheter delivery systems as specified by the manufacturer.
Clinical Applications
Endovascular treatment of intracranial aneurysms in distal and smaller-diameter cerebral arteries.
Suitable for use in anatomies requiring a reduced-profile flow diverter.
Intended to promote aneurysm occlusion through hemodynamic flow disruption across the aneurysm neck.
Clinical suitability and patient selection must follow the manufacturer's Instructions for Use and applicable regional regulatory guidance.
