In the surgery often the blood is running too fast to clot. If the doctors not staunch the flow over time, this may lead to a dangerous loss of blood and to prevent doctors from seeing what they do.
        A team of doctors in Wisconsin working for the U.S. National Institutes of Health are patenting a drastic decision. A bleeding body may be "sewn up" by hitting a dose of energy. The scientists have developed a tool similar to a hairbrush, which is made from stainless steel and small electrodes.
        To stop the blood flowing and close the parts of the body of the patient on time, the instrument is pushed in the matter so that its electrodes break the flowing.
        Radio waves with a frequency around 10 kilohertz are generated by power electrodes, their signals are jumping up and down through the device for about 5 minutes. This invention is sealing the blood vessels and prevents re-bleeding. The patient, of course, is anesthetized and will not feel the procedure.
