BiVACOR Inc is a privately held company founded in Brisbane, Australia in 2008 before expanding to Houston, USA, in 2013. The BiVACOR rotary TAH is designed to be a long-term device that can replace the function of a patientÂ’s native heart. The small, compact device uses proven rotary blood-pump technology to provide the required cardiac output. The BiVACOR system comprises a magnetically levitated rotor located between opposing pump casings. The key feature that enables this device to support both the left and right sides of the heart is the left and right impeller blades, which are mounted on either side of the rotating hub. The hub is levitated and rotated via an electromagnetic motor and bearing arrangement on top of the pump casings. The dedicated hydraulic design of the impellers, combined with state-of-the-art magnetic levitation (MAGLEV) technology, permits control of the circulation to be fine-tuned by means of a differential fluid output. An external controller and batteries provide power to the internal device via a percutaneous driveline.
