Jarvik 2000 - Model VADs - Ventricular Assist Devices (VADs)
The first ventricular assist devices (VADs) developed decades ago were meant to sideline the failing biological heart of a heart failure patient. These pumps were heavy, bulky devices that drew blood from the left ventricle through an intake valve and moved it into the aorta at as much as 10 liters per minute — the full output of a healthy ...

The entire biological heart (except for the atria) is usually removed, and the man-made device is positioned in its place. Most total artificial hearts mimic the natural heart’s rhythm, drawing and pumping blood in pulses. Piston-like pumping actions must be coordinated with inflow and outflow valves. Total artificial hearts therefore require a great deal of complexity ...
