The Terumo Neuro FRED X Flow Diverter Stent (REF XFRED4026) is a self-expanding, dual-layer braided intracranial implant designed for the endovascular reconstruction of the parent artery in the management of intracranial aneurysms. With a nominal labeled size of 4.0 mm diameter and 32 mm total length, this device combines the established FRED dual-layer architecture with the X surface modification, an antithrombogenic hydrophilic polymer coating intended to reduce material thrombogenicity. The device is delivered through a compatible microcatheter and is supplied sterile for single use.

Key Features
- Dual-layer braided design combining an inner low-porosity flow-diverting mesh with an outer high-porosity stent for wall apposition
- X surface modification: covalently bonded phosphorylcholine-based coating engineered to reduce platelet adhesion and material thrombogenicity
- Radiopaque markers and helical tantalum strands to support fluoroscopic visualization of device position and full deployment
- Resheathable and repositionable up to a defined deployment threshold per the Instructions for Use
- Nominal vessel diameter compatibility: 4.0 mm; working length: 32 mm
- Pre-loaded on a delivery wire for controlled deployment through a compatible microcatheter (refer to manufacturer IFU for specific microcatheter compatibility)
- Supplied sterile, single-use

Clinical Applications
- Endovascular treatment of intracranial aneurysms in appropriately selected parent arteries
- Reconstruction of the parent vessel across wide-necked, fusiform or otherwise complex aneurysm morphologies
- Use as part of a neurointerventional flow-diversion strategy by trained physicians in centers equipped for cerebral angiography and neurocritical care
- Indications, contraindications, patient selection criteria and antiplatelet management must follow the official Instructions for Use and applicable local regulatory labeling
