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 XFRED3524) is a self-expanding, dual-layer braided intracranial flow diverter designed for the endovascular treatment of intracranial aneurysms. This configuration has a labelled diameter of 3.5 mm and a working length of 31 mm. The device combines a low-porosity inner braid with a high-porosity outer braid in a single delivery system and incorporates the proprietary X surface modification, a covalently bonded phosphorylcholine-based coating engineered to reduce material thrombogenicity.
Key Features
- Dual-layer braided design combining inner flow-diverting mesh with outer stent-like scaffold in one device.
- X Technology surface modification: covalently bonded phosphorylcholine-inspired coating intended to reduce thrombogenicity of the device surface.
- Labelled dimensions: 3.5 mm nominal diameter x 31 mm working length.
- Radiopaque markers at the proximal and distal ends and helical tantalum strands for fluoroscopic visualization.
- Resheathable and repositionable prior to final deployment, per the manufacturer's instructions for use.
- Microcatheter compatibility: Not specified in the located sources for this exact reference; refer to the current Terumo Neuro IFU/sizing matrix.
Clinical Applications
- Endovascular flow diversion for intracranial aneurysms in vessels sized within the manufacturer's labelled diameter range.
- Intended for use by physicians trained in interventional neuroradiology and endovascular techniques.
- Specific indications, contraindications, and target vessel ranges: refer to the official Terumo Neuro Instructions for Use.
