Abstract
The present invention relates to a pulsatile flow system and method. The pulsatile flow system includes a reservoir, a pressure riser and a first fluid passage connected between the reservoir and the pressure riser. The system further includes a device adapted to expel fluid from the reservoir through the first fluid passage to the pressure riser. A second fluid passage is connected between the pressure riser and the reservoir, and is adapted to allow fluid to flow unidirectionally therethrough, from the pressure riser to the reservoir. The pulsatile flow system may be adapted to provide pulsatile fluid flow through a medical device, such as a ventricle assist device or mechanical heart valve, to replicate a heart's pumping action for testing the device.
