Abstract
One embodiment is a stimulation lead that includes a lead body having a longitudinal surface, a distal end, and a proximal end; and multiple electrodes disposed along the longitudinal surface of the lead body near the distal end of the lead body. The electrodes include multiple groups of segmented electrodes with each group of segmented electrodes having multiple segmented electrodes disposed at a same longitudinal position along the lead. For at least one first group of segmented electrodes, a first pair of the segmented electrodes in the first group are disposed on opposite sides of the lead body and are electrically ganged together by a conductor therebetween.

14. A kit for implanting a stimulation lead into a patient, the kit comprising:
-
a stimulation lead comprising a longitudinal surface, a distal end, and at least one electrode disposed along the longitudinal surface of the stimulation lead near the distal end of the stimulation lead, wherein a portion of the stimulation lead upon which the electrodes are disposed has a non-circular cross-sectional shape; at least one microelectrode lead comprising a distal end and at least one microelectrode disposed at the distal end of the microelectrode lead; and an introducer defining a lumen configured and arranged to receive the stimulation lead, the introducer further comprising at least one interior wall extending into the lumen and defining at least one microelectrode lumen that is configured and arranged to receive, and hold within the microelectrode lumen, a one of the at least one microelectrode leads. - View Dependent Claims (15, 16)

17. A method for stimulating tissue, the method comprising:
-
implanting a lead comprising a longitudinal surface, a distal end, a proximal end, two main portions disposed at the distal end of the lead, a bendable portion disposed between the two main portions, a plurality of electrodes disposed on surfaces of the two main portions of the lead, and a plurality of terminals disposed along the proximal end of the lead and electrically coupled to the plurality of electrodes, wherein the bendable portion is bent so that the two main portions are disposed opposite each other and wherein each electrode has an exposed surface through which electrical energy can be supplied to stimulate adjacent tissue when the stimulation lead is implanted; retaining the lead in the patient with the bendable portion bent; and stimulating adjacent tissue using at least one of the electrodes. - View Dependent Claims (18, 19, 20)
