A device for at least partially occluding an aneurysm is disclosed. The device includes a first elongate member having a distal end. A bridge is positioned proximate the distal end and transformable between a delivery configuration and a deployed configuration. A second elongate member is movable relative to the first elongate member, the first and second elongate members being configured such that one can be moved relative to the other in order to transform the bridge between the delivery and deployed configurations.
