How the DuraHeart LVAS Works
The DuraHeart® LVAS helps the left ventricle pump oxygenated blood throughout the body. Since a failing heart cannot pump enough blood out to the body, the DuraHeart takes over the additional work.
When the pump is activated, the impeller position is precisely controlled by the electromagnetics and sensors to keep it centered within the blood chamber. Permanent magnets attract the impeller to the motor so when the motor spins, it causes the impeller to rotate and pump blood from the heart to the body.
After a DuraHeart is running, some blood continues to flow along its normal route, from the left ventricle directly to the body. However, in its weakened state, the heart is not strong enough to supply sufficient blood for normal activities. The DuraHeart supplements the natural flow by pumping blood from the left ventricle to the aorta, increasing total flow to near normal levels.
Blood enters the DuraHeart Pump through an Inflow Conduit. As the motor magnetically turns the impeller, blood is pumped through the Outflow Conduit out to the body.
