Plasma technology for surface processing of the ruthenium pacemaker electrodes

Abstract

Abstract For pacemaker electrodes, the surface structure elements should be nanometer-sized in order to reduce the capacitive electrical resistance coupling of the electrode with the myocardium tissue. It is proposed to test several approaches. One of them is the creation of the “fuzz” nanostructure on the titanium surface accompanied by the subsequent ruthenium deposition onto this structure. Another one is the formation of the “fuzz” nanostructure on the layer of pre-deposited ruthenium. Such approaches contribute to developing new technology for manufacturing the electric cardiac pacemakers with improved characteristics.
