1. An optical transfer device for tissue treatment, comprising:
an optical probe of a flexible material having a light divergence part at a longitudinal end of the flexible material;
a first coating part extending from the position of the flexible material of the optical probe without the light divergence part and entirely surrounding the light divergence part; and
a second coating part surrounding the first coating part, extending from the position of the flexible material of the optical probe without the light divergence part and entirely surrounding to a longitudinal end of the first coating part,
wherein the first coating part comprises a light diffusion part formed at an end of the first coating part and configured to cover the light divergence part, the light diffusion part having multiple grooves formed thereon,
wherein the second coating part includes multiple grooves formed from the position of the light divergence part to the end of the second coating part in a longitudinal direction, and
wherein the optical transfer device is configured such that the first coating part surrounds the optical probe and the second coating part surrounds the first coating part,
wherein the optical transfer device is a flexible structure, and
wherein the optical transfer device is configured to be directly inserted into or removed from a lumen or tubular lesion tissue of a human body, or a tube is configured to be first inserted into a lumen or tubular lesion tissue of a human body and the optical transfer device is configured to be inserted into or removed from the tube.
