Being the high frequency operation device for egg circular poricidal dehiscence existence blockade

摘要

First and second electrodes which grasp living tissue of PFO, PFO occlusion high-frequency surgical apparatus for the treatment against (PFO) patent foramen ovale in the heart, the living tissue a high-frequency power through the two electrodes a high frequency power supply unit for supplying, an impedance measuring unit for measuring an impedance value by supplying high-frequency power to living tissue, in blood by the electrodes in response to the measured impedance values, for gripping the body tissue and a control unit for determining the grasping condition determining section and the gripping state of the living tissue, according to the determination result, to control the RF power supply at a predetermined power required to perform the action.
