An embolization device includes one or more expansible, hydrophilic embolizing elements non-releasably carried along the length of a filamentous carrier that is preferably made of a very thin, highly flexible filament or microcoil of nickel/titanium alloy. At least one expansile embolizing element is non-releasably attached to the carrier. A first embodiment includes a plurality of embolizing elements fixed to the carrier at spaced-apart intervals along its length. In a second embodiment, an elongate, continuous, coaxial embolizing element is non-releasably fixed to the exterior surface of the carrier, extending along a substantial portion of the length of the carrier proximally from a distal tip. In either of the embodiments, the embolizing elements may be made of a hydrophilic, macroporous, polymeric, hydrogel foam material. In the second embodiment, the elongate embolizing element is preferably made of a porous, environmentally-sensitive, expansile hydrogel that expands, after a predetermined time delay, in response to a change in an environmental parameter, such as pH or temperature.
