Integer Holdings Corporation

One of the world's largest contract manufacturers of medical devices, Integer builds and designs components and finished products for the cardio, vascular, and neuromodulation markets — including implantable batteries that power devices like pacemakers. The company grew out of Wilson Greatbatch Ltd., founded in 1970 by the engineer who invented the first practical implantable pacemaker, after he pioneered the long-lasting lithium-iodine battery that solved early pacemakers' short-lived power problem. In 2016 the firm rebranded as Integer after buying Lake Region Medical — the name means "complete, whole, and comprehensive."
