Abstract: An IS-4 terminal connector assembly includes three terminal electrodes positioned over an inner tubular member such that they are radially offset from one another. Each of the terminal ring electrodes are configured such that they can withstand both tensile and cyclical bending loads with minimal compromise in their outer geometry. Additionally, each of the terminal electrodes is configured such that they have both an inner and outer geometry that facilitates adequate insulation between a select terminal electrode and an adjacent conductor. Additionally, each of the terminal ring electrodes is configured such that they facilitate an external approach to staking a cable conductor.

Abstract: Various embodiments concern an electrode of an implantable medical device for delivering electrical stimulation to tissue. Such an electrode can include a main body formed from a substrate metal comprising one of titanium, stainless steel, a cobalt-chromium alloy, or palladium. The main body may not be radiopaque. The electrode may further include a first coating on at least one side of the main body, the first coating comprising a layer of one of tantalum or iridium metal that is at least about 2 micrometers thick. The first coating can be radiopaque and porous. The porosity of the first coating can increase the electrical performance of the electrode in delivering electrical stimulation to tissue.
