The invention relates to the treatment of aneurysms, and more particularly to intravascular devices and methods for the occlusion of an aneurysm. The device includes a first portion having an expandable and compressible mesh having dimensions for insertion into and expansion against the wall of an aneurysm and a second disk portion having a flexible, collapsible mesh operatively connected to an outer surface of the first portion and having dimensions for covering an outside of the neck opening. The combination of the first portion and second disk portion have a combined resilient flexibility to effectively bias the second disk portion against the neck opening in a substantially flat manner when the first portion is engaged within the aneurysm.
