Abstract
The present invention provides an optical irradiation apparatus including: a dual laser light source unit which simultaneously or selectively outputs multiple light sources created with different outputs; an optical fiber which is connected to the dual laser light source unit, receives the light outputted from the dual laser light source unit, and emits the received light through an embossed end surface; and an inflatable balloon catheter which is formed to surround the embossed end surface of the optical fiber and expands constricted tissue. With the present invention, it is possible to effectively treat constricted tissue during a procedure of performing an anticancer therapy on entire human bodies with various types of cancers, and it is possible to mitigate patient's pain by reducing a relapse rate of stenosis after the photothermal therapy.
