Abstract
An electrical stimulation lead includes a lead body insertable into a patient. Electrodes are disposed along the lead body. The electrodes include at least two sets of segmented electrodes. Each set of segmented electrodes includes a first segmented electrode and a second segmented electrode radially spaced apart from one another around a circumference of the lead body. A tab is disposed on the first segmented electrode of each set of segmented electrodes. The tabs extend into the lead body. A guide feature is disposed on the tabs. The guide features are each radially aligned with one another along the length of the lead body. Conductors extend along the length of the lead body from a proximal end to the electrodes. Each of the conductors is electrically coupled to at least one of the electrodes. At least one of the conductors extends through the radially-aligned guide features of the tabs.
