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.
Claims37
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, wherein said coated assembly is comprised of a substrate and a coating disposed thereon, wherein said coating is comprised of magnetic particles with a particle size in the range of from about 3 to about 20 nanometers, wherein said coating has a top surface and a bottom surface, wherein said bottom surface is contiguous with said substrate, and wherein at least 1.5 times as many of said magnetic particles are disposed near said bottom surface of said stent than near said top surface of said stent.
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, wherein said coated assembly is comprised of a stent and a coating disposed thereon, wherein said coated stent assembly is comprised of a lumen, and biological material disposed within said lumen, and wherein, when said stent is exposed to radio frequency electromagnetic radiation with a frequency of from 10 megahertz to about 200 megahertz, said coated stent assembly has a radio frequency shielding factor of less than about 10 percent, at least 90 percent of said electromagnetic radiation penetrating said stent and contacting said biological material disposed within said lumen.
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, wherein said assembly is comprised of a coating, and wherein said coating that has a relative permeability of at least 1.1 over the range of frequencies of from about 10 megahertz to about 200 megahertz, an increase of such relative permeability over such range of from about 1×10−14 to about 1×10−6 per hertz, and a magnetization, when measured at a direct current magnetic field of 2 Tesla, of from about 0.1 to about 10 electromagnetic units per cubic centimeter.
