Mechanical Recanalization With Flow Restoration in Acute Ischemic Stroke "ReFlow"


Phase 2 Results N/A

Trial Description

The objective of this study is to collect data on the use of the SOLITAIR FR device for treatment of acute ischemic stroke with large artery occlusion i.e. to investigate, whether the application of SOLITAIR is a safe and feasible method for interventional recanalization of large vessels with favorable patient outcome in acute stroke therapy.
