A system for passively anchoring mid-lead electrodes on an endocardial catheter lead includes at least one fibrosis-anchoring opening positioned along the exterior surface of the catheter lead body proximal or distal to the mid-lead electrodes for passively securing the catheter lead against the interior wall of the heart. Within the fibrosis-anchoring openings a suitable material is provided for anchoring the catheter lead body to the heart wall by fibrosis. Preferably, the fibrosis-anchoring openings comprise at least a pair of openings positioned only partially around the exterior of the catheter lead body at locations both proximal and distal to the mid-lead electrodes, with the catheter lead body between the fibrosis-anchoring openings being preformed to bias the mid-lead electrodes against the heart wall.
