MicroPort Willis - Intracranial Stent Graft System

Immediate Occlusion, Effective Exclusion. Willis® Intracranial Stent Graft system is a stent graft solution for the treatment of intracranial aneurysms. The immediate blood flow reconstruction can effectively isolate the blood flow between the aneurysm and the parent artery, while still keeping the blood flow to the parent artery unobstructed. This way, the hemodynamics of the lesion area is reconstructed, and the purpose of aneurysm treatment is achieved.
