简要总结
The primary objective of the study is to determine whether the STARFlex® septal closure system will safely and effectively prevent a recurrent embolic stroke/transient ischemic attack (TIA) and mortality in patients with a PFO and to demonstrate superiority of the STARFlex® device compared to best medical therapy.
