Abstract:
1. A method for forming a helical electrode assembly for carrying a signal associated with an implantable medical device, comprising: forming a first layer on a generally flat substrate; forming a first conducting structure as a second layer upon said first layer, said second layer comprising a first electrode and a first conductive strip operatively coupled to said first electrode; forming a third, non-conductive layer above said first and second layers; forming a second conducting structure as a fourth layer upon said third layer, said fourth layer comprising a second electrode and a second conductive strip operatively coupled to said second electrode; and forming at least a portion of said generally flat substrate and the first, second, third and fourth layers into a helical structure, wherein forming said third layer comprises forming the third layer at an offset position on the second layer such that the third layer does not overlap the region in which the first electrode resides, such that a stair step of layers that contain electrodes and conductive strips is generated.
