Most advanced mini robot for medical use

According to Official Guinness Records,

In April 2009, a team of scientists at the Federal Institute of Technology in Zurich, Switzerland, announced they had constructed a micro-robot capable of swimming in human arteries.
The corkscrew-shaped robot measures a maximum length of 60µm (0.00236 in) and swims in the same manner as a bacteria. The small robot will be used to repair damage to blood vessels and remove arterial deposits that lead to heart and general health problems.
