CPI designed and manufactured the world's first pacemaker with a lithium anode and a lithium-iodide electrolyte solid-state battery.
An improved heart pacer including the conventional combination of a pulse generator, electrode means, and electrode leads coupling the pulse generator to the electrodes, wherein the battery power source of the pulse generator is a solid-state battery with a lithium anode and a lithium-iodide electrolyte.(see Wilson Greatbatch, ed.).
The pacer structure is enclosed in a hermetically sealed metallic enclosure, with means being provided in the enclosure for passing electrode leads in sealed relationship therethrough.
The outer surface of the casing is polished metal*, and is continuous in all areas.
In certain instances, the continuity may be with the exception of the zone through which the external electrode leads pass.

 Lithium-iodide or lithium anode cells became the standard for future pacemaker designs.
