Abstract
In various aspects, the invention relates to an embolic device for treating aneurysms or other vascular disorders that exhibits improved filling and/or neck blockage over conventional devices. As one example, the embolic device can include a structure that is wound into a spiral shape. In some cases, the spirally wound embolic device includes alternating narrow portions and link portions. As another example, the embolic device can be formed from a structure wound to form an infinity shape or, in some cases, multiple infinity shapes. In instances with multiple infinity shapes, the infinity shapes can be arranged either parallel or perpendicular to each other. In certain aspects, the embolic device can include two different embolic devices that are attached by an interconnect element, such that the two devices are attached but have independent freedom of motion when placed within a vascular disorder.
