A central venous catheter (CVC) that includes internal bacterial disinfecting capabilities. According to some implementations the CVC includes a main shaft that is configured for placement inside a patient and an infusion shaft. An optical fiber that includes a first portion and a second portion is configured to emit bacterial disinfecting light with the first portion residing inside at least one of the main shaft and infusion shaft. The CVC further includes a hub wherein the distal end of the infusion shaft is coupled to the proximal end of the main shaft by a conduit located inside the hub. The hub has a first channel that houses the second portion of the first optical fiber.
