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 (REF XFRED3536) from Terumo Neuro is a dual-layer self-expanding braided flow diverter designed for endovascular reconstruction of the parent artery in the treatment of intracranial aneurysms. This configuration is supplied in a 3.5 mm nominal diameter and 40 mm working length, intended for use in appropriately sized cerebral vessels.
Key Features
- Dual-layer braided design combining an inner low-porosity mesh with an outer high-radial-force stent for flow diversion and wall apposition.
- X Technology surface modification engineered to reduce material thrombogenicity.
- Radiopaque markers at proximal and distal ends and helical tantalum strands to support fluoroscopic visualization.
- Self-expanding nitinol construction intended to facilitate vessel conformability.
- Pre-loaded on a delivery system designed for compatibility with standard neurovascular microcatheters; refer to the manufacturer IFU for compatibility details.
- Resheathing and repositioning characteristics as described in the manufacturer Instructions for Use.
Clinical Applications
- Endovascular treatment of intracranial aneurysms via parent artery reconstruction.
- Selection of device length and diameter is based on parent vessel measurements per the manufacturer sizing guidance.
- Intended for use by physicians trained in interventional neuroradiology and flow diversion techniques.
- Indications, contraindications, warnings and precautions are defined in the official Terumo Neuro Instructions for Use; clinicians must consult the IFU and applicable local regulatory labeling prior to use.
