Abstract
A medical device includes a liquid circulation unit that enables transfer of a liquid (a perfusion liquid) supplied from a port unit of a second hub of an energy application device to a distal end portion of a first shaft of a catheter device. The energy application device is relatively movable forward and backward with respect to the catheter device so that an energy application unit can be disposed at a predetermined position on the distal end side of the first shaft.
