The Stryker Surpass Evolve Flow Diverter (REF FD32520, 3.25 mm x 20 mm) is a self-expanding braided cobalt-chromium flow diverting stent designed for endovascular reconstruction of the parent artery in the treatment of intracranial aneurysms. The Evolve platform builds on the Surpass family with a 64-wire braid intended to deliver consistent metal coverage across the labeled diameter range, supporting flow diversion across the aneurysm neck while preserving flow in adjacent perforators and side branches.

Key Features
- Braided flow diverter design: 64-wire cobalt-chromium braid with platinum-tungsten wires for fluoroscopic visibility.
- Labeled dimensions: Nominal vessel diameter 3.25 mm; working length 20 mm.
- Self-expanding delivery: Pre-loaded on a delivery system intended for use through compatible microcatheters.
- Resheathable: Designed to allow partial deployment and resheathing prior to detachment to support precise placement.
- Radiopaque markers: Distal and proximal markers to aid fluoroscopic positioning.
- Single-use, sterile: Sterilized for single patient use.

Clinical Applications
- Endovascular treatment of intracranial aneurysms via parent-vessel flow diversion.
- Reconstruction of the parent artery across wide-necked, large, or fusiform aneurysm morphologies as determined by the treating physician.
- Use within the labeled vessel diameter range as defined by the manufacturer's Instructions for Use.
