There is still a long way to go, and human transplant is years away, but the results so far are extremely encouraging, and the device is a huge step forward in creating an artificial lung, a hope for the 200 million lung disease sufferers worldwide.
Scientists built this prototype by following the natural lung’s design and tiny dimensions; the artificial lung is filled with breathable silicone rubber versions of blood vessels that branch down to a diameter less than one-fourth the diameter of human hair.
