Anterior view of the LVAS showing the inflow canula and outflow conduit. The second image shows the internal components of the VE-LVAS with the ventricular chamber removed, exposing the polyurethane membrane (pale yellow)that performs the pumping of blood, it is driven by its underlying piston (darker grey, round flat component), the rolling cams and electromagnet that move the piston, seal, coupling ring and conduits.

An animation of the electromagnet and the cams rotating is shown here.

An animation of the LVAS in situ with the pump "beatin" can be seen here.
