1. A method of manufacturing an electrode for a lead used to stimulate and sense a body comprising the steps of:

  • forming a raised surface on a distal end of a conductive stem;

    preparing a slurry mixture containing at least one conductive material;

    introducing at least a portion of said raised surface of said conductive stem into said slurry mixture;

    withdrawing said portion of said raised surface of said conductive stem from said slurry mixture such that a portion of said slurry mixture envelopes said raised portion of said conductive stem and covers said distal end of said substrate in a non-uniform thickness; and

    sintering said portion of said slurry mixture enveloping said raised surface.
