The Terumo Neuro FRED X Flow Diverter Stent (REF XFRED2508) is a 2.5 mm diameter x 13 mm length intracranial flow diverter designed for the endovascular treatment of cerebral aneurysms. FRED X builds on the established FRED dual-layer braided design and adds the proprietary X surface treatment, a covalently bonded modification engineered to reduce material thrombogenicity while preserving deliverability and device handling.

Key Features
- Dual-layer braided construction combining a low-porosity inner mesh with an outer stent for flow diversion and wall apposition
- X Technology covalently bonded surface modification intended to reduce thrombogenicity
- Nominal sizing: 2.5 mm diameter x 13 mm length (REF XFRED2508)
- Radiopaque markers at proximal and distal ends and along the device for fluoroscopic visualization
- Designed for delivery through compatible low-profile microcatheters
- Resheathable and repositionable prior to full deployment, per manufacturer instructions for use

Clinical Applications
- Endovascular flow diversion for intracranial aneurysms in appropriately selected vasculature
- Indicated parent vessel diameters and aneurysm characteristics: refer to the current manufacturer Instructions for Use
- Intended for use by interventional neuroradiologists and neuroendovascular specialists in a neurointerventional suite
