Abstract: A method of manufacturing a lead having an electrode includes the steps of introducing a substrate into a mold, creating a negative pressure in the mold, injecting a slurry comprising a binder and a conductive particulate material into the mold cavity during the step of creating negative pressure in the mold cavity, heating the mold having the substrate and the particulate material in an oven to cojoin the particulates and thereby form an electrode, removing the mold from the oven, removing the electrode from the mold, and assembling the electrode into a lead. The produced lead may be used as a steroid eluting pacing cardiac lead.

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.
