We know that people who have coronary problems can be operated through the use of a catheter that is made to reach the place where the problem is. In general, it is usually a narrowing of the vein that, if not corrected, can cause death.<\/p>\n\n\n\n
And although these methods have been used for years and have come a long way, they are still quite imprecise, and since the surgeon must \"see\" the catheter until it reaches the right place, X-ray means have to be used and therefore the patient. receives very high levels of radiation.<\/p>\n\n\n\n
An alternative is the use of mini-robots that move through the veins to the desired location, and once there perform the necessary operation.<\/p>\n\n\n\n
Of course, to operate inside a human artery you need to have a very special mini-robot, and one that also has a very good steering system from outside the body.<\/p>\n\n\n\n
