Abstract
A device for the irradiation of internal cavities of the body includes a flexible catheter, made of a transparent material, containing a fiber optic of which the section at one end is designed to radially diffuse light coming from a source arranged at the other end. An inflatable balloon fixed to one end of the catheter surrounds the diffusing section of the fiber optic. The balloon is made of an elastomeric material that diffuses the light and is prefabricated by molding based on the shape of the cavity to be treated. The balloon presses against the cavity wall and, with the thickness of its surfaces remaining constant after inflation, the pressure needed for inflation is low and cannot damage the cavity tissues.
