ABSTRACT:
Disclosed is a process of thermal treatment in a tissue comprising embedding an implant element in an organism and externally applying a high frequency magnetic field characterized in that the implant element comprises a magnetic exothermic member partially or completely covered with a non-magnetic insulating film.
According to the present invention, the temperature range required in the process of medical treatment in tissue (42.degree. C. to 43.degree. C.) can be more effectively maintained compared with a conventional magnetic exothermic member. Because of the complete coverage with an insulating film, a magnetic exothermic member having a higher Curie temperature than that of the conventional magnetic exothermic member can also be employed. The magnetic exothermic member can provide an isotropic exothermic characteristic when the powders are molded and the components of the magnetic exothermic member never dissolve in a living body.
