Abstract: A hallux valgus correction brace includes: a first insertion piece configured to receive a big toe of a foot; a second insertion piece configured to receive a second toe of the foot; and a gap maintainer coupling the first insertion piece and the second insertion piece, the gap maintainer being configured to apply an elastic force to the first insertion piece and the second insertion piece in a direction away from each other, in which the first insertion piece, the second insertion piece, and the gap maintainer are integrally formed by an elongated member made of metal.

Abstract: A stent is reversibly deformable between a lower-temperature shape and a higher-temperature shape in accordance with temperature changes in a patient's body. The stent has a hollow cylindrical body formed by a plurality of braided filament bodies made of a Ti—Ni alloy of excessive Ni. A lower-temperature shape memorizing process and a higher-temperature shape memorizing process are conducted to the hollow cylindrical body to memorize the lower-temperature and higher-temperature shapes, respectively. The crossing filament bodies are fixed only at the ends of the stent.
