| Zusammenfassung: | Provided is a medical device which can suppress torsion of a wire in a circumferential direction in an expansion body formed using the wire.Amedical device (10) includes an elongated shaft portion (20), and an expansion body (21) disposed in a distal portion of the shaft portion (20) , and configured to expand and contract in a radial direction. The expansion body (21) has wire portions (50) in which a distal portion and a proximal portion are linked with the shaft portion (20), and a holding portion (51) formed using at least one of the wire portions (50), and holding a biological tissue. At least one of a proximal side and a distal side of the holding portion (51) has an opening portion (57) formed using the wire portion (50) or formed using a plurality of the wire portions (50). When the expansion body (21) expands, the wire portion (50) forming the holding portion (51) faces the opening portion (57). |
