Claim 0:
1. A light-irradiation-device delivery apparatus comprising:
a needle tube extending along a longitudinal axis direction, the needle tube having a blade surface disposed at a distal end of the needle tube and a side hole positioned proximally relative to at least a portion of the blade surface, the side hole penetrating from an inner circumferential surface to an outer circumferential surface;
an optical fiber comprising a core allowing light to propagate longitudinally and a clad covering an outer circumferential surface of the core,
the optical fiber being configured to:
be inserted inside the needle tube;
move relative to the needle tube in the longitudinal axis direction; and
emit the light radially from the emission area through the side hole;

wherein the optical fiber is:
movable within the needle tube in the longitudinal axis direction in a first state, and
secured relative to the needle tube in the longitudinal axis direction in a second state such that at least a portion of the emission area radially opposes the side hole.
