Occlusion device

A method, a device, and a system for reproducing a defective blockade are provided. A certain embodiment contains a long and slender main part which has the first lumen, and the first lumen is prolonged toward a distal end from a proximal end of a long and slender main part. in an inside of the first lumen of a main part with a long and slender long and slender structure in which a long and slender structure has a lumen prolonged toward a distal end from a proximal end of a long and slender structure -- at least -- partial -- elasticity -- it is positioned so that rotation is possible and possible. [near the distal end of a long and slender main part], it is combined with some long and slender main parts, and an energy radiation device comes to emit a focused ultrasonic wave.
