1. A method for forming a filtered feedthrough element for an implantable device, the method comprising:

  • providing a feedthrough subassembly that comprises a ferrule, an insulator, an and a pin wherein the insulator being coupled to the ferrule and the pin;

    placing a capacitive element inside the ferrule such that the feedthrough pin slides through an inner diameter of the capacitive element;

    introducing conductive material between the pin and the inner diameter of the capacitive element;

    introducing conductive material between the outer diameter of the capacitive element and the ferrule, wherein the capacitive element includes at least one recessed area at the outer diameter of the capacitive element to form a subassembly; and

    applying heat to the subassembly.
