Provided is a light radiation medical treatment device that can reliably irradiate a required place in a hollow organ with a laser beam. This light radiation medical treatment device comprises: a catheter 20 that can be inserted into a treatment instrument passage 11b formed in a video scope 11 constituting an endoscope system 10; and a light radiator 30 that has an optical fiber probe 32 capable of being inserted into the catheter 20, and causes a laser beam emitted from a laser device 31 to enter from a proximal end side of the optical fiber probe 32 and to be emitted from a light emission section 32a provided to the distal end side of the optical fiber probe 32, wherein the catheter 20 has a cylindrical body section 21 that can be inserted into a hollow organ L of a living body, and a balloon section 22 that is provided to the distal end side of the body section 21 in a manner allowing expansion and contraction in the radial direction of the body section 21, and can, by expanding, bring an outer peripheral surface at least partially into contact with an inner wall of the hollow organ L, and the laser beam emitted from the light emission section 32a passes through the balloon section 22 and is emitted from the outer surface side of the balloon section 22.
