Abstract:
Abstract of the disclosure 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.

A nanoelectrical material with an average particle size of less than 100 nanometers, a surface area to volume ration of from about 0.1 to about 0.05 l/nanometer, and a relative dielectric constant of less than about 1.5, and a chemical/biological sensor comprising such material.
Abstract:
An implantable medical assembly that contains a substrate, and nanomagnetic material and a therapeutic agent located over the substrate. A barrier is located between the therapeutic agent and biological material. When the assembly is exposed to electromagnetic radiation, the barrier between the biological material and the therapeutic agent is removed.
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 of the disclosure A medical device comprised of a coating that inhibits distortion of medical resonance images taken of the device. When the device is exposed to radio frequency electromagnetic radiation with a frequency of from 10 megahertz to about 200 megahertz, at least 90 percent of such radio frequency electromagnetic radiation penetrates to the lumen of the device; and the concentration of the radio frequency electromagnetic radiation that penetrates to the lumen of the device is substantially identical at different points within such interior. The coating is comprised of magnetic material with an average particle size of less than about 40 nanometers.
Abstract:
A shielded substrate assembly that contains a magnetic shield with a layer of magnetic shielding material the magnetic shield has a magnetic shielding factor of at least about 0.5. The magnetic shield contains nanomagnetic material with a mass density of at least about 0.01 grams per cubic centimeter, a saturation magnetization of from about 1 to about 36,000 Gauss, a coercive force of from about 0.01 to about 5,000 Oersteds, a relative magnetic permeability of from about 1 to about 500,000, and an average particle size of less than about 100 nanometers. In one embodiment, the nanomagnetic material contains magnetic material with a coherence length of from about 0.1 to about 100 nanometers.
Abstract:
A contrast-enhancing agent that has a saturation magnetization of at least 1.5 Tesla and that, when contacted with MRI radiation, provides a first gray scale response that is substantially uniform and that has a resolution of at least about 1 millimeter. When the contrast-enhancing agent is repeatedly contacted with said MRI radiation over a period of at least one year, it will repeatedly produce gray scale responses which are substantially identical to the first gray scale response.
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.
