Artificial heart that pumps blood by rotating the impeller floated by magnetism 2000 times per minute
The artificial heart has various challenges, one of which is durable enough to replace the pulsation that reaches about 110,000 times a day and 42 million times a year. An artificial heart using a magnetically levitated impeller may be the culmination of exploring this possibility.

This Maglev Heart Could Keep Cardiac Patients Alive-IEEE Spectrum

Daniel Tims, an Australian biomedical engineer, founded BiVACOR in 2001, a student at Queensland University of Technology. We have been working on the development of a new “artificial heart”. The research created an artificial heart in which a magnetically levitated impeller rotates inside a 650 g body.
The part composition can be seen in the following Sketchfab. Divided into 8 parts, among them, the movable part is the No. 5 impeller and only the motor that rotates the impeller increases the durability.

The material is titanium, a non-corrosive material that hardly causes an immune response. As a feature, a general artificial heart does not have a valve to push out blood with a centrifugal pump, and there is no pulsation when used in the basic mode. However, because it is better for the clinician to see the pulsation when looking at the electrocardiogram, an option to pulsate has been added.
Already, animal experiments using cattle have been conducted, and after 90 days of testing, it was proved that they were able to spend their health.
In the future, those that have reached the clinical stage by the end of 2019 are expected to be completed, and in 2020, a feasibility study request for humans will be submitted to the US Food and Drug Administration (FDA).
