    摘要： A medical device lead is presented that includes an electrode assembly having a first electrode located near a distal end of the electrode assembly and a second electrode located near a proximal end of the electrode assembly. The electrode assembly also includes a conductive elongated coupler that is electrically coupled to the first electrode and capacitively coupled to the second electrode. At low frequencies and DC (e.g., during delivery of stimulation therapy), the capacitive coupling between the conductive elongated coupler and the second electrode presents a high impedance allowing little current to be redirected from the first electrode to the second electrode. However, at high frequencies (e.g., during an MRI scan) the capacitive coupling between the conductive elongated coupler and the second electrode presents a low impedance, resulting in a significant amount of induced current being redirected to the second electrode and dissipated into bodily fluid surrounding the second electrode.
