ABSTRACT:
Thin film devices implantable within a human subject for occlusion of an aneurysm or body vessel are provided. The devices are movable from an elongated, collapsed configuration for delivery to a deployed configuration within the body. Open slots in selected portions of the device telescope as the device moves to its deployed configuration, which causes the associated portions to longitudinally foreshorten and radially expand, while also decreasing in porosity for preventing blood flow. Closed slits in other portions of the device open as the device moves to its deployed configuration, which causes the associated portions to longitudinally foreshorten and radially expand, while remaining open for fluid flow or endothelialization. The occlusion devices may be either self-supporting or supported by a strut structure. Additionally, the occlusion devices may comprise a plurality of mesh layers having unaligned pore systems which further reduce porosity in desired portions of the deployed configuration.
