Abstract
A medical device insertable into a living body lumen includes a drive shaft that rotates in a predetermined direction of rotation in response to a proximal side driving force to transmit a rotational force in a distal direction. The drive shaft includes: an inner coil of plural wires wound side-by-side in a circumferential direction of the drive shaft; and an outer coil of plural wires wound side-by-side in the circumferential direction of the drive shaft and surrounding the inner coil. The inner coil wires are wound in the predetermined direction of rotation in the distal direction as viewed from the proximal side, and the outer coil wires are wound in a direction opposite the predetermined direction of rotation in the distal direction as viewed from the proximal side. The number of wires constituting the inner coil is smaller than the number of wires constituting the outer coil.
