The FRED X Flow Diverter Stent by Terumo Neuro (REF XFRED5014) is a self-expanding, dual-layer braided neurovascular implant designed for endovascular flow diversion in the treatment of intracranial aneurysms. The 5.0 mm x 21 mm configuration is intended for parent vessels in the corresponding diameter range and combines an outer low-porosity inner mesh with an outer stent structure on a single delivery system. The device features the X surface treatment, a covalently bonded biomimetic coating engineered to reduce material thrombogenicity while preserving the mechanical performance of the underlying FRED platform.

Key Features
Dual-layer braided design: Inner low-porosity mesh combined with an outer stent for flow diversion and vessel wall apposition.
X surface modification: Covalently bonded phosphorylcholine-based coating intended to reduce material thrombogenicity.
Tantalum markers: Helical and end markers support fluoroscopic visualization of device length, position and deployment.
Single delivery system: Pre-loaded on a delivery wire designed for controlled deployment, partial resheathing and repositioning prior to detachment.
Self-expanding nitinol construction: Engineered for conformability in tortuous intracranial anatomy.
Sizing: Labeled diameter 5.0 mm, labeled length 21 mm (REF XFRED5014).

Clinical Applications
Intracranial aneurysm treatment: Endovascular flow diversion of intracranial aneurysms in appropriately sized parent arteries.
Wide-neck and complex aneurysms: Used where flow diversion is selected as the endovascular strategy.
Neurointerventional procedures: Delivered via compatible microcatheter systems within a standard neurovascular access setup.
Specific indications, contraindications and warnings: Refer to the official Instructions for Use for the region of intended use.
