The pacemaker generator is a hermetically sealed device containing a power source, usually a lithium battery, a sensing amplifier which processes the electrical manifestation of naturally occurring heart beats as sensed by the heart electrodes, the computer logic for the pacemaker and the output circuitry which delivers the pacing impulse to ...
In 1958, Lillehei was responsible for the world's first use of a small, external, portable, battery-powered pacemaker. It was invented at his behest by Earl Bakken, whose then-small company, Medtronic, designed and repaired electronics for the University of Minnesota hospital. After the introduction of the first widely used prosthetic heart ...
They began designing and testing their implantable cardiac pacemaker powered with a new longer-life lithium battery in 1971. The first heart patient to receive a CPI pacemaker emerged from surgery in June 1973. Within two years, the upstart company that challenged Medtronic had sold approximately 8,500 pacemakers. [3]
Medical device maker Medtronic Plc has disabled internet updates for some 34,000 CareLink programming devices that healthcare providers around the world use to access implanted pacemakers, saying ...

Pacemakers and Internal Cardiac Defibrillators (ICDs) – the function of a VAD differs from that of an artificial cardiac pacemaker in that a VAD pumps blood, whereas a pacemaker delivers electrical impulses to the heart muscle.
Medtronic and Alcatel developed a plutonium-powered pacemaker, the Numec NU-5, powered by a 2.5 Ci slug of plutonium 238, first implanted in a human patient in 1970. The 139 Numec NU-5 nuclear pacemakers implanted in the 1970s are expected to never need replacing, an advantage over non-nuclear pacemakers, which require surgical replacement of ...
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
