Abstract:
1. A high-frequency surgical method for closure of patent foramen ovale, the high-frequency surgical method using a high-frequency probe to close the patent foramen ovale in a heart by application of high-frequency power, comprising: a piercing step of piercing a distal end of the high-frequency probe, which has passed through a blood vessel, from atrial septum through valvula foraminis ovalis, adjacent to the atrial septum; a flexing step of flexing a flexing section installed near the distal end of the high-frequency probe by operating from a proximal end of the high-frequency probe; a hauling step of hauling the high-frequency probe toward a proximal side so as to cause a flexed part of the flexing section to contact a tissue of the valvula foraminis ovalis with the flexing section kept flexed; and a supplying step of selecting at least different combinations of electrodes, a plurality of times, from among three or more electrodes installed at the distal end of the high-frequency probe and supplying high-frequency power for treatment to the selected electrodes.
