Abstract
A method for making an implantable electrode for a cardiac lead includes forming a template including a plurality of features having substantially similar feature dimensions is formed. The template defines a shape corresponding to a shape of the implantable electrode. A layer of conductive material is then deposited on the template such that the conductive material shapes to the plurality of features to define an array of electrode pores having substantially similar pore dimensions in the layer of conductive material. The template is then removed from the layer of conductive material.
