Greatbatch likes to keep its business close to the heart. The company is a leading maker of batteries used in implantable medical devices such as pacemakers and implantable cardioverter defibrillators (ICDs). Other medical components include electrodes, capacitors, and feedthroughs (used to deliver electrical signals from an implantable medical device to an electrode). Greatbatch also makes batteries for demanding industrial applications, such as oil and gas exploration, and supplies power sources for the Space Shuttle. Boston Scientific, Medtronic, Johnson & Johnson, and St. Jude Medical are among the company's top customers. Greatbatch gets nearly half of its sales from US clients.
