Brief Summary:
Prospective, multi-center, randomized 1:1 single blind trial using NOVA sirolimus eluting stent versus Apollo bare metal stent conducted in approximately 15 interventional neurology centers in China. The study was sponsored by Sino Medical Sciences Technology Inc.

Condition or disease Intervention/treatment Phase
Ischemic Stroke Device: NOVA Intracranial Sirolimus Eluting Stent System Device: Apollo Intracranial Stent System Not Applicable

Detailed Description:
The study will enroll 264 subjects overall in two groups (randomized 1:1). The study follow-up will occur at 1, 6 and 12 months post-stent implantation. All patients will undergo angiography assessment (DSA/CTA) at 12 months follow-up. Angiography assessment will be performed at baseline (pre- and post-procedure) and 12 months follow-up.
