Zusammenfassung:	There are provided a medical device and a treatment method capable of breaking an object in a body lumen efficiently with a lower burden on body lumen tissues.A medical device (10) that is inserted into the body lumen so as to crush an object in the body lumen, the medical device including: an elongated shaft (20) that is to be rotatably driven; and a deformable breaking member (60) that is connected to the shaft (20) so as to be rotatable and extends along the shaft (20). The breaking member (60) has a first contact portion (62) and a second contact portion (63) . The first contact portion (62) is located most outward in the radial direction of the breaking member (60) in a state in which the breaking member (60) is expanded radially outward. The second contact portion (63) is located more outward in the radial direction of the breaking member (60) than the first contact portion (62) in a contracted state rather than an expanded state.
