<p>A method of manufacturing 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 medical electrical lead comprises an electrical conductor covered by an insulating 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 consists primarily of mixing a conductive particulate 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 particulate material on the substrate, and sintering the mold, substrate and conductive particulate material to form an electrode.</p> |
