Design outcomes

Primary

Measure	Time frame
1) Successful stent placement, coil mass maintained in cerebral aneurysm at 180 days post DSA, stent open. 2) All-cause mortality within 30 days after surgery and major stroke in the area of stenting attributable to device or therapy	—

Secondary

Measure	Time frame
1) Re-treatment of cerebral aneurysm 180 days after surgery 2) Obstruction or stenosis at the stenting site at 180 days postoperatively 3) Occlusion of cerebral aneurysm after treatment and 180 days postoperatively 4) Hemorrhagic stroke or severe hemorrhage in the first 180 days after surgery 5) Ischemic stroke in the therapeutic vascular territory during the first 180 days after surgery 6) mRS 180 days after surgery 7) Adverse events 7 days postoperatively or until discharge 8) Equipment failure	—
