Abstract: A temporary medical electrical lead includes a connector pin and a single conductor coil. The coil being close-wound and having no turns of the coil distal portion being mechanically coupled together. The coil distal portion translates a force of no greater than 0.1 lbf (0.4 N) when strained 400%.

Abstract: 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.

Abstract: Described herein is a device configured to be implanted into a live human or animal. The device includes an electrically non-conductive frame; one or more electrical components disposed in the electrically non-conductive frame; and a self-supporting film. The self-supporting film forms a hermetical seal with the electrically non-conductive frame. The self-supporting film and the frame enclose the electrical components. The device is configured to be implanted into a live human or animal. Also described herein is a method of making a device configured to be implanted into a live human or animal. The method includes providing an electrically non-conductive frame comprising one or more feedthroughs, openings and a cavity; disposing electrical components within the cavity; optionally filling the cavity with a material to embed the electrical components in the material; and sealing the openings by applying a self-supporting film to the one or more openings.
