ABSTRACT:
A method of manufacture for a medical electrical lead, and in particular, a method of manufacturing a sintered porous platinized electrode used in a steroid eluting pacing cardiac lead which offers increased dimensional and shape consistency over previously used manufacturing methods. The method of manufacturing the electrode consists primarily of mixing a conductive material and a binder to form a slurry, introducing a distal end of a substrate into a mold, creating a negative pressure in the mold, injecting the slurry into the mold to form a mass of conductive material on the substrate, and sintering the mold, substrate and conductive material to form an electrode.
