(57) [Summary] [PROBLEMS] To provide a device for preventing an acute coronary artery occlusion and restenosis in angioplasty and performing the angioplasty in a safe state within a short time. The centralized control unit 500 detects the pressure, temperature, and cavitation state inside the balloon provided at the tip of the hot balloon catheter 300 via the balloon state measurement transmission unit 600, and the centralized control unit 500 displays the liquid. By controlling the injection unit 100 and the balloon dilatation liquid reflux internal pressure control unit 200 to dilate the stenotic lesion site with a balloon, the balloon heating energy generation unit 400 is controlled while dilating to heat the liquid Q for a short time, and the endovascular membrane Heat-transform. |
