artificial heart

artificial heart
a titanium pump that is implanted into the body to take over the function of a failing left ventricle in patients with heart disease. This allows the diseased ventricle time to recover its function. The pump is powered by an external battery, strapped to the patient's body, to which it is connected by wires passed through the patient's skin. Originally pumps were implanted into the abdomen, but the most recent devices are small enough to fit into the heart itself.
