Abstract:
1. A device for use in occluding an aperture, the device comprising: a first post; a second post; a plurality of arms, each arm comprising a first radial section extending outward from the first post, a second radial section extending outward from the second post and a loop comprising a greater than 360 degree helical turn connecting the first and second radial sections; and first and second sheets attached to each arm, each sheet having an inside face and an outside face, the inside faces facing inwardly toward one another, and the outside faces of the first and second sheets facing outwardly away from one another and toward the first and second posts, respectively, wherein the first sheet is positioned along an inside length of each first radial section and the second sheet is positioned along an inside length of each second radial section such that each first and second radial section extends radially along and contacts at least a portion of the outside face before extending over an outer peripheral edge of the first and second sheets, respectively, and the loops extend between the inside faces of first and second sheets, each loop having a radial innermost portion that passes through and engages an edge of the aperture so that the loops create a flexible inner diameter capable of self-centering the device with respect to the aperture.
