The BiVACOR is a total artificial heart designed to fully take over function for a failing heart. About 5.1 million people in the United States suffer from heart failure and with limited donor hearts available, BiVACOR seeks to extend the lifespan of patients with end-stage heart failure who are either waiting for a transplant or do not qualify for one. The unique technology in the BiVACOR system includes a magnetically levitated rotor with impellers placed on either side to support the left and right sides of the heart.
