The MAESTRO registry is a post-market, single-arm, non-interventional, multicenter registry
Electronic platform to collect real-world clinical data, evaluate and periodically report safety and effectiveness of CE approved and commercially available Microvention devices used for the endovascular treatment of Intracranial aneurysms and acute ischemic stroke.
Note: For the purposes of this protocol, ancillary/accessory devices such as balloon catheters, carotid stent for extracranial stenosis and other access devices are not considered primary treatment devices. Further, devices used for rescue following attempt of a different primary treatment device are not considered initial primary treatment devices.

Device: All Microvention Class III implantable device CE marked
Cohort 2 will focus on data collection on all Microvention Class III device CE marked used in the treatment of Acute Ischemic Stroke
Device: All Microvention Mechanical Thrombectomy Class III device CE marked
