Abstract
Apparatus and methods are provided for occluding blood vessels and other anatomical structures. Occlusion devices are delivered percutaneously and extraluminally through a small gauge needle and include expandable elements that are deployable on opposite sides of a target vessel to be occluded. When positioned about the vessel the elements are expanded and brought together to compress and occlude the vessel. Embodiments include those adapted for temporary as well as permanent use.
