1. An intracavitary electrode device for a high-frequency capacitive heating device, comprising:
- a flexible member adapted to be inserted at a leading end portion thereof into an intracavity of an endotract organ of a living body;
a cap-shaped electrode disposed around said leading end portion covering both of an end surface of said leading end portion and a circumferential surface of said leading end portion, said circumferential surface being adjacent to said end surface;
a flexible polymer film enclosing said cap-shaped electrode so as to form a gas-tight space in association with said cap-shaped electrode and said flexible member, and secured on said flexible member at one end thereof;
an introducing passage disposed in said flexible member for introducing a cooling medium into said gas-tight space; and
a discharging passage disposed in said flexible member for discharging said cooling medium from said gas-tight space,each of said introducing passage and said discharging passage communicating with said gas-tight space.

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.
