context_page_description: Cardiac Pacemakers, Inc., doing business as Guidant Cardiac Rhythm Management, manufactured implantable cardiac rhythm management devices, such as pacemakers and defibrillators. It also sold insulin pumps controlled by microprocessors and various equipments to regulate heart rhythm. In addition, Cardiac Pacemakers, Inc. developed therapies for the treatment of irregular heartbeats. The company was founded in 1971 and is based in St. Paul, Minnesota. Cardiac Pacemakers, Inc. operates as a subsidiary of Boston Scientific Corporation.
context_section_description: 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.
