摘要： An assembly for shielding an implanted medical device from the effects of high-frequency radiation and for emitting magnetic resonance signals during magnetic resonance imaging. The assembly includes an implanted medical device and a magnetic shield comprised of nanomagnetic material disposed between the medical device and the high-frequency radiation. In one embodiment, the magnetic resonance signals are detected by a receiver, which is thus able to locate the implanted medical device within a biological organism.

摘要： A medical device includes a pattern of electrically conductive material. The pattern of electrically conductive material has an anti-antenna geometrical shape such that the anti-antenna geometrical shape substantially prevents the medical device from creating an imaging artifact and/or substantially allows imaging of a volume within the medical device. The pattern may be formed by multiple “figure-8” shaped electrical conductors, multiple “figure-8” emulating electrical conductors, multiple sine-wave-like shaped electrical conductors, multiple zig-zag patterned electrical conductors, by multiple electrical conductors, each having sequential conductive loops, and/or a single conductor weaved into a loop mesh. The electrically conductive material may be titanium, tantalum, nitinol, stainless steel, and/or NbZr.

摘要： A medical assembly includes a multi-wire lead having a plurality of coiling loops. The multi-wire lead has a gap region and a non-gap region. The gap region has adjacent coiling loops of the multi-wire lead with gaps therebetween so as to form different impedance in the gap region than impedance in the non-gap region. The non-gap region has adjacent coiling loops of the multi-wire lead with no gaps therebetween. The gaps may provide inter-loop capacitance. The multi-wire lead may have a plurality of gap regions, each gap region having a non-gap region therebetween.
