An implantable endocardial, multi-lumen lead wherein the distal end of the lead body is cored to provide a stopped bore cooxial with the axis of the lead body. A distal electrode is inserted into the stopped bore without an additional tubular segment and glue joint. A first lumen in the lead body has an axis which is offset from the axis of the lead body itself. A low voltage conductor passes through the first lumen. A second lumen is also offset from the axis of the lead body. The lumens may have a circular or other cross section. A plurality of non-coaxial lumens may be provided.
