As an axial flow device, the HeartMate II® produces no pulsatile action. Weighing 12 ounces (about 375 grams) and measuring about 1.5 inches (4 cm) in diameter and 2.5 inches (6 cm) long, it is significantly smaller than other currently approved devices.
How does HeartMate II work?
HeartMate II is designed to take over the pumping function of the patient’s left ventricle. The device is placed just below the diaphragm in the abdomen. It is attached to the left ventricle, and the aorta, the main artery that carries oxygenated blood from the left ventricle to the entire body.
