The Levitronix is a magnetic levitation blood pump. It is designed for short term support of the circulation in patients with post cardiotomy shock (failure to wean from cardio-pulmonary bypass). It is manufactured by Levitronix, a company that specialises in bearingless technology. Bearingless blood pumps offer advantages over blood pumps with bearings in terms of thrombogenicity and durability. Levitronix is also involved with development of the Heartmate III ventricular assist device.
