1. A medical device comprising:
an elongated shaft portion;
an expansion body disposed in a distal portion of the shaft portion, the expansion body configured to expand and contract in a radial direction;
the expansion body including a holding portion, the holding portion including a proximal side holding portion and a distal side holding portion, the proximal side holding portion and the distal side holding portion configured to hold a biological tissue, and a movable portion configured to displace the holding portion in a holding direction configured to hold the biological tissue between the proximal side holding portion and the distal side holding portion;
the expansion body configured to be stored in a storage sheath in a contracted state and to expand in the radial direction by a self-expanding force of the expansion body when exposed outward of the storage sheath; and
wherein the movable portion is configured to displace the holding portion in the holding direction when the expansion body expands in the radial direction by the self-expanding force of the expansion body, and to expand in the radial direction with the proximal side holding portion and the distal side holding portion after holding the biological tissue between the proximal side holding portion and the distal side holding portion.
