System and method of using endobronchial ultraviolet light therapy to treat patients infected with COVID-19 coronavirus, SARS, CoV-2

A catheter for performing ultraviolet light therapy in a pulmonary system of a patient, comprising:

• a) an elongated flexible catheter body defining a longitudinal axis and having opposed proximal and distal end portions;
• b) a handle assembly operatively associated with the proximal end portion of the catheter body;
• c) an illumination assembly operatively associated with the distal end portion of the catheter body and configured to emit ultraviolet light radiance to reduce viral, fungal and/or bacterial loads in the pulmonary system of the patient, wherein the illumination assembly includes a first LED light source facing in a first direction, a second LED light source facing in a second direction, and a third LED light source facing in a third direction, and wherein a first quartz glass window disposed in a first plane extending perpendicular to the longitudinal axis of the catheter body is distally adjacent to the first LED light source, a second quartz glass window disposed in a second plane extending parallel to the longitudinal axis of the catheter body is laterally adjacent to the second LED light source, and a third quartz glass window disposed in a third plane extending parallel to the longitudinal axis of the catheter body is laterally adjacent to the third LED light source;
• and
• d) an elongated braided sleeve disposed within the catheter body and extending along a length thereof for serving as a heat sink for the illumination assembly.
