The medical device includes a catheter that has a first lumen into which a medical wire is insertable. The medical device also has a tube-shaped body proximal to the catheter, and the tube-shaped body includes a second lumen which communicates with the first lumen. A delivery mechanism is accommodated in the second lumen of the tube-shaped body. The delivery mechanism enables a delivery operation for moving the medical wire distally beyond the distal end of the medical device by a predetermined movement amount.
