Abstract
The surface of an implantable, porous stimulating electrode particularly intended for use in pacemakers is provided with a thin coating of a hydrophilic polymer in which is embedded an anti-inflammatory steroid. The electrode reduces the postoperative increase in the stimulation threshold, as well as the growth of connective tissue, without any reduction in capacitance.
