Implantable medical systems include implantable percutaneous medical leads and/or implantable medical lead extensions that have fewer conductors than distal electrodes, or distal connectors for extensions, by having one or more conductors be electrically coupled to multiple distal electrodes. The multiple distal electrodes may span a general area of a body of a patient that includes a specific point that requires therapy, such as multiple vertebral segments. Because all distal electrodes spanning the general area that are coupled to an active conductor will output the stimulation therapy, the specific point within the general area will receive the therapy even without identifying which electrode is most effective. Bipolar and unipolar stimulation modes may be used. Multiple leads may be used where each lead has more distal electrodes than conductors. Additionally, a single lead may have more distal electrodes than conductors while also carrying multiple stimulation waveforms.
