InVAD ia a continuos-flow, centrifugal type rotary blood pump that is placed outside the body. The continuous flow design means that the patient may not have a pulse. Can be used as a solution for acute heart failure while longer time options are considered.

InVAD ventricular assist system is a magnetically levitated centrifugal-flow pump that can be applied rapidly in the operating room. By providing flows of up to 5 L/min, this pump can safely support a patient’s circulation for 2 weeks or longer.The system comprised of console, a pump motor driver, a flow probe and a flat screen control monitor. Providing a contact-free, friction-free environment, technology can result in 10% low haemolysis, 5% low device-related thrombosis and, improved end-organ function.  This technique may facilitate ambulation and recovery in selected patients.InVAD left ventricular assist device system can be used for perioperative or postcardiotomy circulatory support of the failing heart. The device resides at the patient’s bedside, and the cannulae are usually inserted through a midline sternotomy, with the inflow cannula in the left ventricle or right superior pulmonary vein and the outflow cannula in the aorta.
