  • REDUCTION OF RF INDUCED TISSUE HEATING USING CONDUCTIVE SURFACE PATTERN
    Publication number: 20090099555
    Abstract: The present invention provides, among other things, means to suppress AC current propagation along elongated medical devices incorporating long conductive structures. AC currents in the frequency range from approximately 10 MHz to 3 GHz can be substantially suppressed without altering the low and DC frequency response of the medical device.
