Abstract
Medical leads having at least one segmented row of electrodes, as well as at least one ring electrode that extends substantially completely around the periphery of the lead, are described. The electrodes in a segmented row extend around only a portion of the periphery of the lead, rather than substantially around the entire periphery. The electrodes in a segmented row may be distributed at respective locations around the periphery of the lead and separated by insulating material. The ring electrodes and segmented rows are located at respective axial positions. For example, in some embodiments, a plurality of segmented rows, such as two rows having three electrodes each, are located between two ring electrodes. Such a lead may, for example, provide a variety of stimulation modalities because of localized stimulation capabilities.
