Internal Robotics?

... Microbots' Fantastic Voyage Through Your Clogged Arteries
"Finally, Fantastic Voyage is becoming reality — well, almost. Rather than mini Raquel Welches scuba diving through your veins, picture teeny-tiny insects. Researchers at the Korea Institute of Science and Technology are building six-legged robots small enough to skitter through your blood vessels. The critters can crawl for up to 10 days, no batteries required. Their biocompatible skeletons — made of the same stretchy stuff that's in Silly Putty — are plated with heart cells from rats. When immersed in a glucose solution, the cells beat in synchrony. With each pulse, the bot's back legs contract, pushing the bug forward at a "speed" of 100 micrometers per second (50 meters a week). Lead scientist Sukho Park believes such devices could be injected into humans to treat cardiovascular disease as early as 2020. Once inside a clogged vessel, the bot would feed off the glucose in the blood as it creeps along the length of the artery, releasing a dissolving agent to clear blockages and plaque. Sure, but how will it look in a formfitting wet suit?"
