    摘要： An assembly for protecting biological tissue from the effects of heating. The assembly contains a conductor in contact with the biological tissue and forming an electrical circuit comprising the biological tissue. The assembly contains a device for modifying the impedance of the electrical circuit such that, at a frequency of from about 10 megahertz to about 150 megahertz, such impedance is at least about 0.5 ohms per centimeter of length of said conductor. The assembly also contains a device for limiting the flow of current through the biological tissue such that, when the assembly is exposed to an alternating current electromagnetic field at a frequency of 64 megahertz and a magnetic field strength of 1.5 Tesla for 15 minutes, the temperature of the biological tissue does not exceed 42 degrees Celsius.
