Abstract
An implantable device is provided by a process that includes preparing a substrate which has a low impedance carbon coating over a porous substrate. The carbon coating is a carbon lattice formed by plasma depositing a hydrocarbon within an energized gaseous environment. The implantable device is one into which tissue ingrowth is desired, such as electrodes for cardiac and neurostimulation.
