摘要
This invention is an aneurysm occlusion device with a sequence of shape-changing embolic members which travel through a lumen into an aneurysm sac. The longest axes of these members are substantially parallel to the lumen as within the lumen and longest axes of these members are substantially parallel to the circumference of the neck of the aneurysm after the member exit the lumen. This device can fill a greater percentage of an aneurysm sac, better reduce blood circulation into the aneurysm sac, and better conform to an irregularly-shaped aneurysm sac than coils or single hollow mesh structures.
