The Stryker Surpass Evolve Flow Diverter (REF FD45025) is a self-expanding, braided flow diversion stent designed for the endovascular treatment of intracranial aneurysms. This configuration features a 4.50 mm vessel diameter and a 25 mm working length, intended for placement across the aneurysm neck to redirect blood flow and promote progressive aneurysm occlusion while preserving flow in adjacent branches and perforators.

Key Features
- 64-wire braided construction combining cobalt-chromium and platinum-tungsten filaments for radiopacity and consistent mesh density
- Self-expanding design engineered to maintain wall apposition across a range of parent vessel diameters
- 4.50 mm nominal diameter x 25 mm length configuration for medium to large parent vessels
- Pre-loaded delivery system intended for use with a compatible microcatheter
- Mesh architecture designed to support flow diversion across the aneurysm neck while preserving side-branch flow
- Radiopaque markers to support fluoroscopic visualization during deployment

Clinical Applications
- Endovascular flow diversion treatment of intracranial aneurysms
- Reconstruction of diseased parent artery segments
- Cases requiring a 4.50 mm diameter device with a 25 mm landing zone
- Use within indications, vessel sizing and patient selection criteria defined in the official Instructions for Use
