ABSTRACT:
An electrical medical lead is provided having two or more electrodes, electrically insulated from each other and electrically coupled to individually insulated filars in a multi-filar coiled conductor. When the lead is used with a medical device equipped with a switch matrix, electrodes are selected individually or simultaneously to serve as an anode or cathode in any unipolar, bipolar or multi-polar configuration for delivering stimulation and/or sensing signals in excitable tissue. In one embodiment, a tip electrode array is expandable for improving electrode contact with targeted tissue and stabilizing lead position.
