The researchers at Case Western Reserve University were fully aware of the failings of modern artificial lungs, which is why they developed a futuristic replacement: the CWRU lung.

If you're one of the 200 million people worldwide living with lung disease, I don't have to tell you how inadequate contemporary solutions are. Whereas today's replacement lungs are expensive, external and temporary, the CRWU lung is a remarkable facsimile of the actual organ. Instead of forcing patients to carry around heavy oxygen tanks, Case Western's lung is efficient enough to use plain and simple air.

For now, prototypes of the CRWU lung are externally attached, but their genius design promises an implantable version in the near future. Don't procrastinate quitting cigarettes just yet, however, because clinical trials for the artificial lung aren't set to begin for another decade!
