One or more multi-electrode lead couplable with a medical device, such as an implantable medical device. Each lead includes a lead body extending from a lead proximal end portion to a lead distal end portion. The proximal end portion includes a connector assembly for connection to the medical device. An intermediate or distal end portion includes two or more electrodes and a drug region shared by at least two of the electrodes. In one example, the drug region is positioned between two or more electrodes such each of the electrodes may benefit from a drug in the region. In another example, the medical device comprises circuitry adapted to sense a heart in a first instance and stimulate the heart in a second instance using a selected electrode configuration. A method of forming a lead having a drug region shared by more than one electrode is also discussed.
