Abstract:
1. An electrode for cortical stimulation, comprising: a flexible generally planar substrate configured to be implanted proximate to a cortical region of a brain of a patient; a first contact group carried by the substrate, the first contact group having a first electrical contact, a second electrical contact, and a first fixed electrical shunt between the first and second electrical contacts such that the first and second electrical contacts are electrically interconnected to each other; a second contact group carried by the substrate, the second contact group having a third electrical contact, a fourth electrical contact, and a second fixed electrical shunt between the third and fourth electrical contacts such that the third and fourth electrical contacts are electrically interconnected to each other, wherein the first and second electrical contacts of the first contact group are not in conductive electrical communication with the third and fourth electrical contacts of the second contract group, at the substrate; a first lead electrically coupled to the first contact, with the first lead and the first shunt forming a first electrical path having a mechanical discontinuity at the substrate; and a second lead electrically coupled to the third contact, with the second lead and the second shunt forming a second electrical path having a mechanical discontinuity at the substrate.
