A method of manufacturing a medical electrical lead and, in particular, a method of manufacturing a sintered porous platinized elec- trode used in a steroid eluting pacing cardiac lead which offers increased dimensional and shape consistency over previously used manufacturing methods. The medical electrical lead comprises an electrical conductor covered by an insulat- ing sleeve, a connector coupled to one end of said electrical conductor, an electrode coupled to the opposite end of the electrical conductor for conducting electrical energy to and from a body. The method of manufacturing the electrode con- sists primarily of mixing a conductive particulate material and a binder to form a slurry, introduc- ing a distal end of a substrate into a mold, cre- ating a negative pressure in the mold, injecting the slurry into the mold to form a mass of con- ductive particulate material on the substrate, and sintering the mold, substrate and conductive par- ticulate material to form an electrode. |
