Willem Kolff
In the mid 1950’s a dutch man named Willem Kolf invented the first ever artificial heart. This artificial heart was only used in animals. This device was also air-driven and had two pumps. Dr. Jarvick used his principles on the Jarvick 7. The dog lasted 90 minutes on Kolff’s machine.

The Jarvik 2000
The Jarvik 2000 was a major upgrade to the Jarvik 7. Instead of having to stay in the hospital they had a belt that let the patient be mobile. This device was made out of titanium and had only one cable. This was powered by electrical power.APA Citation: Jarvik 2000 Heart - Texas Heart Institute - Heart Assist Devices. (n.d.).

The Abio Cor
The abio cor only weighed three pounds and the battery only weighed four. The significance of this innovation was that it was wireless. And it was the first self-contained artificial heart. This was only used for patients at the end of the stage for heart failure.

Temporary Artificial Heart
The syn cardia was invented at this time and was air driven. The pump could pump 9.5 liters of blood a minute. This device was non-movable, but it was only temporary. It was the size of a washing machine and weighed 418 pounds.

Syn Cardia Freedom
The most reliable device is the Syn Cardia freedom. This device could be used at home. It had a driver in it to power it. and it also was a backpack. This innovation is still used today. This was the worlds first wearable power supply backpack with a Total Artificial Heart. APA Citation: Clinical Trials. (n.d.). SynCardia Systems, Inc.
