Abstract
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.
