Brief Title
REal-World Analyses of Stroke - Thrombus Occlusion REtrieval
Detailed Description
This is a prospective, multi-center, single arm, observational, Real World Evidence (RWE) post-market study with two cohorts.
The primary objective of Cohort I of the RESTORE study is to determine the proportion of subjects achieving successful revascularization (mTICI ≥ 2b) with the SOFIA® Flow Plus 6F Aspiration Catheter when used in conjunction with the direct aspiration as first line treatment technique for patients with acute ischemic stroke in the anterior circulation based on collection of real-world evidence data. Secondary objectives include the evaluation of good functional outcome (defined as mRS ≤ 2 at day 90), revascularization time, and procedure related major neurological complications, all based on real-world evidence data collected.
The objective of Cohort II of the study is to evaluate standard outcomes such as successful revascularization (mTICI ≥ 2b), good functional outcome (defined as mRS ≤ 2 at day 90), revascularization time, and procedure related major neurological complications based on real-world evidence data. Additional outcomes may be defined and research questions generated based on review of the collected data.
