An occluding device designed for occlusion of fluid flow through a body cavity is disclosed. The device comprises a coil having a proximal portion and a distal portion extending longitudinally from the proximal portion. The coil has an initial tension along the distal and proximal portions and is configured have a general helical shape in an expanded state. The device further comprises a first set of fibers attached to the coil and extending therefrom for occlusion of the body cavity. The device further comprises a second set of fibers attached to the coil at a plurality of areas longitudinally along the coil, defining an occlusion sail disposed longitudinally along the coil at the plurality of areas therealong. The second set of fibers is configured have the general helical shape when the coil is in the expanded state for enhanced occlusion of the body cavity.
