Coiled sheet valve, filter or occlusive device and methods of use

Abstract

Abstract Apparatus (20) is provided comprising a coiled sheet (21) having a plurality of flaps (28) mounted on its interior surface that project radially inward into a lumen (30) formed by the interior surface of the apparatus when it is deployed. The flaps (28) lie parallel to the interior surface of the sheet during transluminal delivery, but project radially inward once the apparatus (20) is deployed. The flaps (28) may comprise a fine mesh for uses 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 (30). In a further alternative embodiment, the flaps (28) may comprise a resilient biocompatible plastic or polymer, so that the flaps (28) move in response to the flow, and function as a pressure-based or directional valve.
