Title:
DEVICE FOR LOCAL HEATING AND STEREORESONATOR FOR LOCAL HEATING
Document Type and Number:
WIPO Patent Application WO/1989/007469
Kind Code:
A1
Abstract:
A local heating device used for the thermotherapy by applying high-frequency energy to areas to be heated such as an affected part of a human body to heat it, and a stereoresonator for such heating. The stereoresonator is constituted of a conductor having a cavity with a recess which forms an internal electrode for generating concentrated electric field for heating. Such an electrode may alternatively be made of a separate conductor. High-frequency energy is supplied to the stereoresonator from a high-frequency power supply. The provision of the internal electrode helps generation of an electric field having a high degree of concentration. Therefore, the body can be sufficiently heated to the depths and a desired part is heated in a concentrated manner, thus improving the therapeutic effect.
