摘要： The position of a metal marker 5 relative to an optical fiber 6 is fixed, and the metal marker 5 can be moved up close to a target site such as a thrombus. It is preferable that the position, in an optical fiber longitudinal direction, of a front-end face of the optical fiber 6 is coincident with the position, in an optical fiber longitudinal direction, of a front-end face of the metal marker 5. More specifically, since the distance between the target site and the front end of the optical fiber 6 is known by radiography, it becomes unnecessary to use a large quantity of contrast agent and irradiate a laser beam depending on skill and intuition, and therefore an effective laser beam irradiation becomes possible.

摘要翻译： 金属标记物5相对于光纤6的位置是固定的，并且金属标记物5能够靠近靶位置如血栓移动。 优选的是，光纤6的前端面的光纤长度方向与金属标记5的前端面的光纤长度方向的位置一致。 更具体地说，由于通过射线照相方法已知目标部位与光纤6的前端之间的距离，所以根据技能和直觉，不需要使用大量的造影剂并照射激光束，因此有效 激光束照射成为可能。
