Moscow-Sana
Scientists of the Russian National Research University Itmo in Petersburg have devised a new method that allows to eliminate catheters and use shoring nets that threaten the patient's health.
Russia Today website quoted the university's media office as saying in a statement today that scientists have created soft robots that are controlled by a magnetic field and can be used to treat blood clots.
The statement added that this method of treatment is safer than its counterparts and will reduce in the future the interventions in the body, protect the inner walls of blood vessels from damage, and reduce the formation of new clots.
For her part, Anna Pozitkova, an engineer at the International Research Center of Itmo University, said: We plan to insert the robots into the blood vessel in the form of a soft tape, but under the influence of a rotating magnetic field, it is converted into a spiral shape that goes to the place of the clot, like a drill wraps the clot and connects it and after connecting it it returns With him under the influence of the magnetic field to the starting point where the doctor lifts it from the blood vessel.
Pozitkova added that the movement of the robots is programmed by means of the magnetic field, and thanks to its remote control, it does not harm the blood vessels when moving. The length of the robot is 15 mm and its width is 2 mm, which allows it to move easily through deep veins as well as access to hard-to-reach places. The authors of the program pointed out that The robot has successfully passed all laboratory tests.
