摘要:
A high-frequency surgical PFO closure apparatus used to treat patent foramen ovale in the heart includes a first and second electrodes which grasp living tissue of the patent foramen ovale a high-frequency power supply section which supplies high-frequency power to the living tissue via the electrodes an impedance measuring section which measures an impedance value by supplying high-frequency power to the living tissue a grasping condition determining section which determines, based on the measured impedance value, a grasping condition regarding how the living tissue is grasped in blood by the electrodes and a control section which controls high-frequency power supply at a predetermined power level needed to treat the patent foramen ovale, according to a result of the determination.
