Feasibility Study of the LVIS™ (Low-profile Visualized Intraluminal Support)Device

With the stent-assisted technique to treat wide neck intracranial aneurysms, the neurovascular stent is placed across the aneurysm neck, to act as a bridge to prevent coils from protruding into the parent artery. Stenting may allow to more safely achieve a higher packing density of coils. These effects may improve the rates of complete aneurysm occlusion and enhance the durability of the coiling treatment.The LVIS™ device manufactured by MicroVention, Inc. has a braided design which may provide superior conformability and parent artery apposition, as well as a more reliable continuous and uniform neck bridging than other neurovascular stents.
