ABSTRACT:
An electrode device for heating a tumor in an endotract organ by high frequency convergent electric current has a container of a flexible polymeric material provided with thick side wall, a thick bottom wall connected to one end of the side wall and an opening defined by the other end of the side wall. The device further has a deformable electrode member disposed near an inner surface of the thick bottom wall, and a flexible polymeric film fluid-tightly attached to the other end of the thick side wall. A mesh-like member of a flexible polymeric material is disposed between the electrode member and the flexible polymeric film, and has a plurality of first passages leading to a top surface thereof and a bottom surface thereof, and a plurality of second passages each communicating the first passages with each other.
