Coiled sheet valve, filter or occlusive device and methods of use
First Claim
1. Apparatus implantable within a body vessel or organ, the apparatus comprising:
- a tubular member having an interior surface defining a lumen, the tubular member comprising a rolled sheet having a longitudinal edge, the tubular member having a reduced diameter for transluminal delivery wherein the sheet is coiled to form overlapping turns, and an expanded diameter when deployed in the body vessel or organ; and
a plurality of flaps disposed circumferentially adjacent to one another from the interior surface of the tubular member, each one of the flaps defining a substantially planar or curvilinear surface having side edges, the flaps projecting radially inward into the lumen so that the side edges overlap when the tubular member is in the deployed state.

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.

14. Apparatus implantable within a body vessel or organ to provide a therapeutic result, the apparatus comprising:
-
a tubular member having an interior surface defining a lumen, the tubular member formed by rolling a sheet having first and second longitudinal edges, a plurality of teeth arranged along the first longitudinal edge and a plurality of openings arranged along the second longitudinal edge, the tubular member having a contracted state of reduced diameter for transluminal delivery wherein the sheet is rolled to form a series of overlapping turns, and a deployed state of expanded diameter wherein the plurality of teeth engage the plurality of openings in the second longitudinal edge; and a plurality of flaps disposed from the interior surface of the tubular member, the flaps projecting radially inward into the lumen when the tubular member is in the deployed state. - View Dependent Claims (15, 16, 17, 18, 19, 20)
