How does the Jarvik 7 work?

The Jarvik 7 is a type of artificial heart designed to replace the biological heart in patients with severe heart failure. It consists of a pneumatic pump that circulates blood through the body, driven by air pressure generated by an external console. The device is implanted in the chest and connected to the patient’s vascular system, allowing it to take over the heart's pumping function. The Jarvik 7 requires a power source and continuous monitoring, making it a temporary solution while patients await a heart transplant.
