An occlusive implant includes an elongated member having an end, a portion proximal to that end, and a portion distal to that end. The proximal portion is sufficiently flexible so that it can be folded upon itself and maintain that configuration without further restraint. At least a portion of the distal portion is preformed to have a first configuration when in a first state and a second configuration when in a second state. The distal portion second configuration has a flow resistance substantially greater than that of the proximal portion. When discharged in the region to be occluded, the proximal portion is forced into a mass around at least a portion of the distal portion secondary structure. As the mass builds in size, it is believed to frictionally engages the surrounding vasculature wall and anchors the implant thereto. The occlusive implant preferably is provided in an introducer cartridge for delivery in vivo.
