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 XFRED5514) from Terumo Neuro is a self-expanding, dual-layer braided intracranial implant configured at 5.5 mm nominal diameter by 22 mm working length. FRED X builds on the FRED platform by adding a covalently bonded surface modification (X Technology) intended to reduce material thrombogenicity while preserving the device's mechanical and deployment characteristics.
Designed for endovascular reconstruction of the parent artery, the device combines a low-porosity inner braid with a high-porosity outer stent in a single delivery system, enabling single-step placement and intra-procedural visibility.
Key Features
Dual-layer braided design: inner flow-diverting mesh and outer stent in one device.
X Surface Technology: covalently bonded hydrophilic phosphorylcholine-based coating intended to reduce material thrombogenicity.
Tantalum radiopaque markers: full-length helical markers and distal/proximal flared bands support fluoroscopic visualization.
Resheathable and repositionable prior to final detachment to support accurate placement.
Pre-loaded delivery system compatible with standard neurovascular microcatheters as specified by the manufacturer's IFU.
Nominal sizing: 5.5 mm vessel diameter, 22 mm working length.
Clinical Applications
Endovascular flow diversion in adult patients, used by trained neurointerventional specialists in accordance with the manufacturer's Instructions for Use and applicable local regulatory clearances. Specific indications, vessel ranges, and contraindications are defined in the official IFU and may vary by region; please refer to the IFU for clinical suitability.
