摘要： A medical electrical lead having a conductor assembly covered by an insulating layer, and a shield covering positioned adjacent or proximate to at least a portion of the insulating layer in order to shield the conductor assembly from one or more electromagnetic fields. The shield covering is formed of a polymer-matrix composite. The polymer-matrix composite includes a polymeric resin having discontinuous conductive fillers provided therein. The discontinuous conductive fillers include one or more of nano-sized metal structures and nano-sized non-metallic conductive structures. The nano-sized non-metallic conductive structures can have a coating formed of one or more metals. The nano-sized non-metallic conductive structures can be formed of carbon. In turn, the nano-sized non-metallic conductive structures can include one or more of carbon nanofibers, carbon filaments, carbon nanotubes, and carbon nanoflakes.

摘要： A medical electrical lead having a conductor assembly covered by an insulating layer, and a shield covering positioned adjacent or proximate to at least a portion of the insulating layer in order to shield the conductor assembly from one or more electromagnetic fields. The shield covering is formed of a material that is electrically conductive, where the material is in a wrapped or woven form. The material is selected so as to have an effective combination of small size and high conductive surface area, e.g., as opposed to metal wire or coatings thinner than metal wire. As such, the shield covering exhibits sufficient conductivity in the presence of one or more high frequency electromagnetic fields so that interference to the operation of the conductor assembly is minimized. The material can have a coating formed of one or more metals. The material can include carbon. In turn, the carbon can be formed of one or more of carbon fiber, carbon nanofiber, and single or multi-walled carbon nanotube.

摘要： A prosthetic heart valve includes an annular stent having annularly spaced commissure portions. The tips of the commissure portions are preferably covered with fabric, and then additional fabric covers that fabric and the remainder of the stent, both inside and out (possibly also including a sewing ring insert at or near the base or inflow edge). The fabric is then covered by a layer of tissue, again both inside and out. A single sheet of additional tissue is mounted around the outside of the previously assembled components. This additional tissue forms the leaflet portions of the valve. The leaflet portions of the additional tissue are shaped by contact with a shaped mandrel, and the tissue of the structure is subjected to fixation (e.g., cross-linking) to produce a completed valve.
