The Stryker Surpass Elite Flow Diverter (REF FDE45020) is a self-expanding braided intracranial implant with a labeled diameter of 4.5 mm and a working length of 20 mm. It is engineered for endovascular flow diversion across the neck of intracranial aneurysms, redirecting blood flow along the parent artery to support intra-aneurysmal stasis and progressive aneurysm occlusion while preserving flow in adjacent perforators and branches.

Key Features
- Braided flow-diverting design intended to provide consistent metal coverage across the aneurysm neck.
- Nominal sizing: 4.5 mm diameter x 20 mm length, supplied preloaded on a delivery system.
- Self-expanding construction for conformability to parent vessel anatomy.
- Radiopaque markers to support fluoroscopic visualization during navigation, deployment and post-deployment assessment.
- Single-use, sterile packaging configuration consistent with the Surpass Elite product family.
- Compatibility with the dedicated Surpass Elite delivery system as defined by the manufacturer's instructions for use.

Clinical Applications
- Endovascular flow diversion for intracranial aneurysms in vessels matching the labeled diameter range.
- Treatment planning for wide-necked, large or complex aneurysms where flow diversion is selected by the treating neurointerventional team.
- Use as part of a documented neurointerventional procedure performed by qualified physicians, in accordance with the manufacturer's IFU and applicable local regulatory clearances.
