Abstract
A high-frequency capacitive heating electrode device comprises a cap-shaped electrode, a flexible support for supporting the electrode with one end thereof capped with the electrode, a flexible polymer film which surrounds the electrode and forms a gastight space between the support and the flexible polymer film, and passages for respectively introducing and discharging a cooling medium to and from the gastight space. The high-frequency capacitive heating electrode device is disposed in the vicinity of the target portion of a living body to be heated and is useful for the hyperthermia therapy for a cancer of the uterine cervix.
