"First-generation devices pumped blood in a pulsatile manner, but the devices now pump with continuous flow either from an axial-flow pump (e.g. HeartMate II) or centrifugal/outward-flow pump (e.g. HeartMate 3 and HeartWare HVAD System). As a result, patients have no palpable pulse or a greatly diminished pulse 2."

"The LVAD acts as a conduit, diverting blood from the left ventricle, through a mechanical pump, to the aorta. There are several different brands available; one commonly used device is the HeartMate II (Thoratec, Pleasanton, California) pictured in this article. The HeartMate II consists of an inflow cannula that diverts blood from the apex of the left ventricle into a pump. The pump then propels blood forward through an outflow Dacron graft to the ascending aorta. An electrical cable connects the LVAD to an external power source carried with the patient 1,4."
