Abstract
This invention can be embodied in a method and device for therapeutically-occluding a cerebral aneurysm. A method embodiment includes radially-constraining a tubular mesh to form proximal and distal convex portions of the mesh, collapsing the proximal portion into a concave (e.g. bowl) shape, and expanding the distal portion of the mesh within an aneurysm sac by filling it with embolic members and/or material. The expanded distal portion of the mesh holds the concave proximal portion securely against the aneurysm neck and conforms to the wall contours of even an irregularly-shaped aneurysm sac.
