This invention is an intrasacular aneurysm occlusion device with a proximal resilient stent which becomes wider than the aneurysm neck and a distal flexible net which is expanded by being filled with embolic members. The stent and the net work together. The stent occludes the aneurysm neck and prevents the device from slipping out. The net conforms to the walls of even an irregularly-shaped aneurysm sac and keeps the stent pressed against the inside of the aneurysm neck. This has advantages over the prior art, especially for aneurysms with irregularly-shaped sacs.
