HOW ARTIFICIAL HEART TECHNOLOGY WORKS
An artificial heart is a type of man-made mechanical device that replaces the human heart in a patient’s body. The average human heart beats 60 to 100 times per minute with the right and left atria pumping blood to their respective ventricles at the same time. The ventricles then contract together to push blood out of the heart and into the body.
ARTIFICIAL HEART TRANSPLANT PROCEDURE
The man-made heart transplant procedure is an open heart surgery that requires the chest to be opened in order to operate on the heart muscle, valves, arteries, or other areas of the heart such as the aorta or vessels.
RECOVERY
Recovery time varies greatly by patient depending on the patient’s condition before the surgery. The hospital stay following surgery may last one month or even longer. Following heart surgery, the patient can expect to remain in the intensive care unit for several days before transitioning to a standard hospital room.
How does an artificial heart work?

What is the purpose of an artificial heart?
Originally designed by Richard Wampler, OHSU’s artificial heart creates a blood flow that mimics a natural pulse. It replaces the human heart’s two lower chambers, the ventricles, with a titanium tube containing a hollow rod that moves back and forth. This back-and-forth motion pushes blood to the lungs so it can extract oxygen and then move the oxygenated blood through the rest of the body.

Can an artificial heart be charged?
OHSU’s artificial heart will probably need to be charged with a small, hand-held battery pack outside the body. But the hope is that a smaller, more efficient battery could eventually be implanted under the skin and be recharged from the outside.
Overview
An artificial heart is a device that replaces the heart. Artificial hearts are typically used to bridge the time to heart transplantation, or to permanently replace the heart in the case that a heart transplant (from a deceased human or, experimentally, from a deceased genetically engineered pig) is impossible. Although other similar inventions preceded it from the late 1940s, the first artif…
History
A synthetic replacement for a heart remains a long-sought "holy grail" of modern medicine. The obvious benefit of a functional artificial heart would be to lower the need for heart transplants because the demand for organs always greatly exceeds supply.
Although the heart is conceptually a pump, it embodies subtleties that defy straightforward emulation with synthetic materials and power supplies. Consequences of these issues include s…
