Abstract
The present invention provides a medical device including: an insertion part having a longitudinal axis; a first balloon and a second balloon attached to the insertion part; and a fluid supply path through which a fluid is supplied to the first balloon and the second balloon. The first balloon can be expanded and contracted and is movable in the longitudinal-axis direction. The second balloon can be expanded and contracted and is disposed closer to a distal end side than the first balloon is. One end of the second balloon is fixed to the distal end of the insertion part, and the other end of the second balloon is fixed to the first balloon. The fluid supply path has a connecting flow path communicating between the first balloon and an inner space of the second balloon. The second balloon is expanded after the first balloon is expanded, by supplying the fluid.
