Abstract
An occluding device for occlusion of fluid flow through a body cavity is disclosed. The device comprises an embolization coil formed from at least one wire strand and having an initial tension. The embolization coil is defined by a primary coil formed into a secondary coil. The primary coil has a primary shape defined by a linear longitudinally extending coil having a plurality of helical turns and is helically wound into the secondary coil, wherein the secondary coil has a series of axially spaced apart loops. The axially spaced apart loops are larger than the helical turns of the primary coil. The embolization coil is movable between an expanded state for occlusion of a body cavity and a collapsed state for delivery or retrieval. An absorbent material, including at least one of cotton and regenerated cellulose, is attached to the embolization coil and extends therefrom. A kit is also included.
