New Type Of Artificial Lung Created

cylonlover writes "Researchers have created an artificial lung that uses air as a ventilating gas instead of pure oxygen — as is the case with current man-made lungs, which require heavy tanks of oxygen that limit their portability. The prototype device was built following the natural lung's design and tiny dimensions and the researchers say it has reached efficiencies akin to the genuine organ. With a volume roughly the same as a human lung, the device could be implanted into a person and even be driven by the heart."
