Conditions

Acute Ischemic Stroke Due to Intracranial Large Artery Occlusion

Brief summary

This study is a prospective, open-label, multi-center, registry study, designed to to documents that EmboTrap II usage as a thrombectomy device for emergency large vessel occlusion (ELVO) in terms of the rate of First Pass Recanalization (FPR). Patients with ELVO will initially underwent mechanical thrombectomy usig EmboTrap II. FPR is defined as modified Tissue Thrombolysis In Cerebral Ischemia (mTICI) 2b or 3

Interventions

DEVICEThrombectomy using EmboTrap II

The subjects will receive endovascular treatment for acute stroke according to standard clinical practice. Specifically, using a stent retriever, contact aspiration EmboTrap II. The number of thrombectomy attempts is at the operator's discretion. Combination of balloon guide catheter or intermediate catheter is recommended.
