This is a real device called an LVAD (left ventricular assist device). .
LVADs are surgically implanted mechanical heart pumps which are used for patients suffering from heart failure and other heart diseases. The device is sometimes called a "bridge to transplant" but is now used in long-term therapy. People awaiting a heart transplant must wait for a long time before a suitable heart becomes available from a donor. During this wait, the patient's heart may deterioriate and become unable to pump enough blood to sustain life. An LVAD can help a weak heart and "buy time" for the patient or eliminate the need for a heart transplant. The LVAD doesn't replace the heart, it just helps it do its job. This can mean the difference between life and death for a person whose heart needs a rest after open-heart surgery or is too weak to effectively pump on its own.. The function is pretty simple, the LVAD has a tube that pulls blood from the left ventricle into a pump. The pump then sends blood into the aorta. This effectively helps the weakened ventricle to do its job properly, and relieves symptoms such as shortness of breath. A Permenant LVAD is currently being used in some terminally ill patients whose conditions makes them inteligible for heart transplantation...Case by our friends @themedicalmentors
