The VitalFlow Centrifugal Pump is a blood pump designed to move blood by centrifugal force generated by a combination of a smooth rotating cone and low-profile impeller fins. Energy is transferred from the pump in the form of pressure and velocity as the blood is driven toward the outlet port of the pump. To limit friction and heat generation, the VitalFlow Centrifugal Pump utilizes a pivot bearing design on a dual ceramic pivot. The pump’s blood contacting surface is coated with Balance Biosurface which is a non-heparin biocompatible coating that reduces platelet adhesion. The VitalFlow Centrifugal Pump couples to a remote magnetic drive unit called the VitalFlow™Motor Drive, which interfaces with a pump speed controller. It also couples with the VitalFlow™ Emergency Hand Crank in the event of controller or power failure.
A device intended to be connected to a drive unit (not included) to circulate blood through the extracorporeal circuit of a non-roller type cardiopulmonary bypass system, via a centrifugal force mechanism, for gas exchange and reinfusion; it may in addition be used in extracorporeal support systems for ventricular support/circulatory assistance. It includes flow channels and a rotor driven by the system’s drive unit. This is a single-use device.
