Abstract
Lead electrodes having an asymmetrically distributed current density and methods for imparting current density directionality in lead electrodes are described. An implantable medical lead includes a lead body having a proximal section that connects to another implantable device and a distal section having a pre-biased shape configured to secure the lead to an inner wall of a body vessel. An electrode coupled to the distal section of the lead body includes a conductor mass having an asymmetrically distributed current density that imparts a directionality to one or more active portions of the electrode.
