An implantable cardioverter defibrillator (ICD) including a set of leads having electrodes disposed therein. The electrodes may include a weld electrode connected to an internal wire of the lead and the ICD and a tip electrode. The tip electrode may have a set of grooves or cut out regions in its outer surface to provide edge effects for currents applied through the tip electrode. The grooves or cut out regions may form gaps in the surface of the tip electrode exposing a medical compound that is housed within the tip electrode. The medical compound may elute through the gaps.
