A deformed nail corrector for correcting a deformed nail is provided that includes: a first elastic wire which has one end portion thereof fixed to one edge of the deformed nail in a width direction; a second elastic wire which has one end portion thereof fixed to the other edge of the deformed nail in the width direction; and a binding means which binds the first and second elastic wires to each other and is slidable along the first and second elastic wires in a bound state. The first and second elastic wires are brought into a state where the first and second wires are deformed along the deformed nail with the first and second, elastic wires being in a corrector mounting state where the first and second elastic wires are bound to each other by the binding means.

An intravascular obstruction removing wire includes an elongate wire body, at least two non-branched wire portions having distal ends and proximal ends which are connected to a distal end of the wire main body, and a plurality of filament portions extending across the wire portions. The non-branched wire portions and the filament portions form a trapping portion. The trapping portion is deformable from a large-diameter state in which the non-branched portions branch to the distal end of the wire body forward in different directions and the filament portions are separated from each other, so that a space surrounded by the non-branched wire portions and the filament portions is formed to trap therein an obstruction in a blood vessel, to a small-diameter state in which the non-branched wire portions are positioned so that a distance between the wire portions is smaller than that of the wire portions in the large-diameter state.
