ABSTRACT:
Apparatus is provided comprising a coiled sheet having a plurality of flaps mounted on its interior surface that project radially inward into a lumen formed by the interior surface of the apparatus when it is deployed. The flaps lie parallel to the interior surface of the sheet during transluminal delivery, but project radially inward once the apparatus is deployed. The flaps may comprise a fine mesh for use as a filter, or alternatively may be covered with a biocompatible material that is substantially impermeable, so as to partially or completely occlude the lumen. In a further alternative embodiment, the flaps may comprise a resilient biocompatible plastic or polymer, so that the flaps move in response to the flow and function as a pressure-based or directional valve.
