An artificial heart with a magnetically suspended impeller that rotates 2,000 times per minute to pump blood

There are many challenges to overcome with artificial hearts, one of which is durability, which is enough to replace the heart's beat, which is about 110,000 times a day, or 42 million times a year. The artificial heart that uses a magnetically levitated impeller may be the culmination of our exploration of this possibility.

Daniel Timms, an Australian biomedical engineer, founded BiVACOR, an artificial heart manufacturer, in 2001 while he was a student at the Queensland University of Technology. He has been working on the development of a new 'artificial heart.' The result of his research is an artificial heart in which a magnetically levitated impeller rotates inside a 650g body.

You can see the parts configuration in the Sketchfab below. It is divided into eight parts, and the only moving parts are the fifth impeller and the motor that rotates the impeller, which increases durability.

The material used is titanium, a non-corrosive material that hardly induces an immune response. One of its features is that it does not have the valves found in typical artificial hearts because it uses a centrifugal pump to push blood out, and when used in basic mode, it does not pulsate. However, because it is better for clinicians to be able to see the pulsation when looking at an electrocardiogram, the option to pulsate has been added.

Animal testing has already been conducted on cows, and it has been proven that they are healthy after 90 days of testing.

The company expects to have a clinical trial ready by the end of 2019, and will submit a request for a human feasibility study to the U.S. Food and Drug Administration (FDA) in 2020.
