A device for capturing an obstruction in a vasculature can include a first elongated member (115), an expandable element (112), an invertible element (113), and a gap (125) positioned between the expandable element and the invertible element sized to be placed across the obstruction. The expandable element and the invertible element can be positioned near the distal end of the first elongated member. The expandable element can expand from a collapsed delivery configuration to an expanded configuration. The invertible element can expand from a collapsed delivery configuration to an expanded configuration, and the invertible element can invert from the expanded configuration to an inverted configuration, thereby forming a pocket (122). The pocket can envelope at least a portion of the gap and can thereby capture an obstruction that is in the gap.
