The study is a prospective, multicenter, open-label, single arm post market follow-up registry designed to demonstrate the potential treatment of intracranial, saccular aneurysms with the Next Generation Neuroform Stent System. The study will evaluate the permanent morbidity and mortality rate within the 12 to 16 months following the procedure. The study will evaluate as well the percent occlusion of the treated target lesion on angiography in the absence of retreatment, or parent artery stenosis at the target location at 12 to 16 months. Subjects with documented saccular aneurysms arising from a parent artery may potentially benefit from stent assisted coiling, provided they meet the other eligibility criteria.
