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 Terumo Neuro FRED X Flow Diverter Stent (REF XFRED2513) is a self-expanding, dual-layer braided flow diverter designed for the endovascular reconstruction of intracranial arteries affected by aneurysms. With a labeled size of 2.5 mm diameter x 18 mm length, this configuration is intended for small-caliber intracranial vessels. The device features the X surface modification, a covalently bonded phosphorylcholine-based coating engineered to reduce material thrombogenicity while preserving the established FRED dual-layer architecture.
Key Features
- Dual-layer braided design combining an outer low-porosity stent and an inner high-porosity stent in a single delivery step.
- X surface modification intended to reduce thrombogenicity of the device surface.
- Self-expanding nitinol construction with radiopaque markers for fluoroscopic visualization of both stent ends and the working length.
- Pre-loaded delivery system compatible with standard neurovascular microcatheters as specified by the manufacturer IFU.
- Resheathable and repositionable prior to full deployment, per manufacturer instructions for use.
- Vessel diameter: 2.5 mm nominal.
- Working length: 18 mm nominal.
Clinical Applications
- Endovascular flow diversion treatment of intracranial aneurysms in appropriately sized parent vessels.
- Reconstruction of small-caliber intracranial arteries where a 2.5 mm x 18 mm flow diverter is indicated.
- Use within neurointerventional procedures performed by trained operators.
- Specific indications, contraindications, and patient selection criteria: refer to the official Terumo Neuro FRED X Instructions for Use.
