Engineered Organ Transplants

Although people can survive and lead relatively normal lives with just one kidney, I can see the world's first implantable artificial kidney benefiting more than a few individuals. Considering that the organ donor list isn't as long as the donee list, I'm sure you won't disagree.

Developed by researchers at the University of California in San Francisco, this implantable artificial kidney "would include thousands of microscopic filters as well as a bioreactor to mimic the metabolic and water-balancing roles of a real kidney," according to Neatorama. Clinical trials are expected to begin in a few years.
