[Problem] To provide an ablation system capable of suppressing a thermal injury to a luminal membrane. [Solution] An ablation system (10) equipped with: an ablation device (11) provided with a balloon (21) on the tip end of a shaft (22), an in-side tube (27) for conveying a fluid into the balloon (21) and positioned along the shaft (22), a shaft (22) internal space for discharging the fluid from the balloon (21) and positioned along the shaft (22), and an optical fiber (29) for guiding a laser beam into the balloon (21) and positioned along the shaft (22); a laser-beam generation means (12) for irradiating the optical fiber (29) with the laser beam; and a fluid circulation means (13) for circulating the fluid in the internal space of the balloon (21). Therein, the ablation device (11) has a reflecting material (33) for reflecting the laser beam emitted by the optical fiber (29) in the balloon (21), and the reflecting material (33) is capable of moving inside the balloon (21) in the axial direction (191), and also capable of rotating with the axis thereof being the axial direction (101). |
