Acquisition & Mergers

CPI was a highly successful start up venture, increasing sales from zero in 1972 to over $47 million and highly profitable when it was acquired by Eli Lilly and Company in 1978 for $127 million. During the 1970s, Lilly acquired other medical device companies including IVAC of San Diego, Physio Control of Redmond WA, and Advanced Cardiovascular Systems of Santa Clara, CA. These companies formed the core product/therapy areas of the Medical Devices Division of Eli Lilly and Company.^[2]

World's first use of the lithium battery

CPI designed and manufactured the worlds 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.^[3]

World's first lithium battery powered pacemaker

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