Abstract:
1. An apparatus that galvanically releases antimicrobial ions, the apparatus comprising: a substrate; and a coating on the substrate comprising an anodic metal that is co-deposited with a cathodic metal on the substrate to form a non-uniform mixture of the anodic and cathodic metals, wherein the coating comprises a plurality of microregions or microdomains of anodic metal in a matrix of cathodic metal or a plurality of microregions or microdomains of cathodic metal in a matrix of anodic metal, the microregions or microdomains forming a continuous path of interconnected veins of anodic metal within the matrix of cathodic metal or a continuous path of interconnected veins of cathodic metal within the matrix of anodic metal, wherein the continuous path extends from an outer surface of the coating to the substrate; further wherein the anodic metal is galvanically released as antimicrobial ions when the apparatus is inserted into a subject's body.
