Artificial lung
An artificial lung was a prosthetic device that was implanted into a body to replace biological lungs.

In 2371, while discussing Neelix's stolen lungs, Captain Kathryn Janeway suggested they fit him with a pair of artificial lungs. The Doctor explained that it would be too complicated to replicate replacements for his lungs, as his respiratory system was " directly linked to multiple points along his spinal column." ()
