A stent formed of a metallic material having a two-way memory adapted to be retrieved or repositioned after delivery includes an elongated tubular body and at least one crown connected to a respective longitudinal end of the body, the crown including a plurality of unconnected leaves, each leaf having a longitudinally extending frame connected at one end to the end of the body. A method of manufacturing the stent so that the crown has a greater two-way memory effect than the body is disclosed.
