Scientists created the device which will allow to travel on brain vessels.
Within 40 years scientists worked over creation "the traveler on vessels" and here, at last, the device which could move on narrow vessels of a brain, in those places where the usual kateterny tube can't reach, appeared. Thus the main problem consisted in creation not the mechanism, and the motor which would allow the device to move against a blood-groove. The Australian scientists managed to create such motor which in diameter is less, than two human волоса.
Now researchers achieve permission to carry out test for animals, they hope that by means of their motor this device - "traveler" can successfully destroy blood clots, to deliver drugs to necessary fabrics and to do a biopsy.
