A type of radiosurgery known as radiofrequency or radio wave surgery is based on cutting tissue with high frequency alternating current. This surgical procedure is very different form traditional electro-surgery and other types of electrocauterization because it can simultaneously cut and coagulate tissue without using any kind of physical pressure.

The basis of radiofrequency is the use of high frequency radio waves of 4,0 MHz to create low temperature through radiofrequency microfiber electrodes. The difference between this method and electrosurgery, is that the tissue serves as resistance instead of electrodes. That means there is no heating of microfiber electrodes thanks to the low temperature created by the radio wave energy. Instead, the tissue intracellular water provides resistance and vanishes without the need for heating and damaging, as in electrosurgery. Such treatment in tissue results in haemostasis (arrest of bleeding) without additionally damaging the tissue. In addition, there is no hazard or shock caused by burns.
