1. A lead, comprising:
- a lead body defining a longitudinal surface, a distal end, and a proximal end, wherein the lead body has a non-circular cross-sectional shape;
two main portions disposed at the distal end of the lead body;
a bendable portion disposed between the two main portions and thinner than the two main portions;
a plurality of electrodes disposed on a surface of each of the two main portions of the lead to form at least one column of electrodes on each of the two main portions; and
a plurality of terminals disposed along the proximal end of the lead body and electrically coupled to the plurality of electrodes,wherein each column of electrodes comprises at least two of the electrodes and wherein the bendable portion is configured and arranged to bend so that the two main portions are disposed opposite each other.

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.

13. 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 along 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; 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 at least one microelectrode lumen, a microelectrode lead. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
