Provided are: a medical device which is capable of expanding inside a lumen of a living organism, and which is capable of cutting an object from the inner wall surface of the lumen of the living organism, while reducing the burden on the living organism and damage to the device; and a treatment method. This medical device (10) for cutting an object inside a lumen of a living organism is provided with: a rotatable drive shaft (60); a strut (41) which is rotatably coupled to the distal side of the drive shaft (60), extends along the rotational axis (X), and has a central section capable of expanding outwards in the radial direction; and a support part (50) which is rotatably coupled to the distal side of the drive shaft (60), is provided with a plurality of gaps, is formed so as to be mesh-like and tubular, has at least one section positioned inside the strut (41) in the radial direction, and is capable of expanding outwards in the radial direction as a result of a central section thereof in the direction along the rotational axis (X) being bent. |
