The conductor has a resistivity at 20 degrees Centigrade of from about 1 to about 100 microohm-centimeters. The insulating matrix is comprised of nano-sized particles having a maximum dimension of from about 10 to about 100 nanometers. The insulating matrix has a resistivity of from about 1,000,000,000 to about 10,000,000,000,000 ohm-centimeter. The nanomagnetic material has an average particle size of less than about 100 nanometers. The layer of nanomagnetic material has a saturation magnetization of from about 200 to about 26,000 Gauss and a thickness of less than about 2 microns. The magnetically shielded conductor assembly is flexible, having a bend radius of less than 2 centimeters.

A process for coating a superconductive film onto a substrate is provided. In the first step of this process, a solution of the reagents required to produce the superconductive material is subjected to ultrasonic sound waves to create an aerosol. Thereafter, the aerosol is contacted with plasma while being subjected to substantially atmospheric pressure and a radio frequency alternating current in excess of 100 kilohertz; a vapor is produced in this step. The vapor so produced is passed through an orifice and allowed to deposit onto a substrate, which is in contact with a substrate holder which is electrically grounded.

摘要:
A marking material that, when disposed upon medical devices used during interventional medical procedures with imaging modalities such as X-ray Fluoroscopy and Magnetic Resonance Imaging, renders such medical devices visible with minimal imaging artifacts. The material comprises a particulate material with generally higher atomic weight disposed within a matrix material with generally lower atomic weight. In one embodiment the particulate material is magnetic. In another embodiment the particulate material is non-magnetic.
