US Patent 10046070 Disinfecting methods and apparatus

According to one implementation a central venous catheter is provided that include a main shaft and an infusion shaft. The main shaft has a proximal end, a distal end and a working lumen, the distal end configured for placement inside a patient. The infusion shaft has a proximal end, a distal end and a working lumen. The assembly further includes an optical fiber that is configured to emit bacterial disinfecting light. The distal end of the infusion shaft is coupled to the proximal end of the main shaft by a conduit located inside a hub. The conduit fluidly connects the working lumen of the infusion shaft with the working lumen of the main shaft. The hub has a channel that houses at least a portion of the length of the optical fiber.
