Abstract
The present invention provides, in certain embodiments, unique products and methods for occluding vascular vessels. Implantable devices useful in some inventive embodiments include at least two expandable occluding members, e.g., self-expandable sponge form devices, with an intermediate segment extending between the members. These devices are preferably compressible for placement in a delivery device lumen for delivery to a vascular vessel site. Upon deployment in the vessel, each of the members expands to occlude the vessel at a separate vessel location with the intermediate segment occupying space in the vessel between the two members. Optionally, the intermediate segment can be constructed to provide a hollow or other interior region for receiving one or more materials, for example, to receive an injectable fill material after one or both of the expandable members have been deployed.
