Abrégé
(EN)

A medical device is disclosed which can suppress torsion of a wire in a circumferential direction in an expansion body formed using the wire. A medical device is disclosed, which enlarges a biological tissue. The medical device includes an elongated shaft portion and an expansion body disposed in a distal portion of the shaft portion. The expansion body has a wire portion configured to expand and contract in a radial direction, and a torsion restriction portion that restricts movement of the wire portion in a circumferential direction of the expansion body.
