Abstract:
An implantable medical device comprised of a lumen. When the device is, at different points in time, exposed to two different radio frequency electromagnetic radiations, one of whose frequencies differs from the other by a factor of at least 1.5, at least 90 percent of each of the radio frequency electromagnetic radiations penetrates to the lumen of the device.
Abstract:
A coated assembly with an inductance of from about 0.1 to about 5 nanohenries and a capacitance of from about 0.1 to about 10 nanofarads. The coated assembly contains a stent and a coating. When the assembly is exposed to radio frequency electromagnetic radiation with a frequency of from 10 megahertz to about 200 megahertz, at least 90 percent of the electromagnetic radiation penetrates to the interior of the stent.

Abstract:
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.
Abstract:
A metallic stent that, when it is contacted with an input alternating current electromagnetic field and a static magnetic field that contacts biological matter located within the stent, an output signal is produced that that has a fixed phase relationship with the input signal and that has a magnitude that is at least about 0.01 times as great as the magnitude of the input signal.
