Artificial Heart Implanted
Surgeons in the American state of Kentucky have implanted the world's first self-contained mechanical heart. The unnamed patient is said to be resting comfortably. The implant is the first of five human trials licensed in America. The hospital that made history is releasing few details: The artificial heart was implanted on Monday. The patient, an American, is said to be comfortable and responsive.
Hospital Official: The quiet period is necessary; it's in the best interest of the patient and of the physician. It's in the best interest of patient care.
This heart replacement device is the product of decades of research. It is self-contained within the body, powered by an internal battery, which is itself recharged by a clip-on external battery pack.
Doctor: If it fulfills its promise, people will be able to engage in full exercise and activities and will not be tethered down by the external machine that does the pumping.
Thousands of patients in America are waiting for heart transplants. One day the new breed of mechanical heart might offer a viable alternative but for now it's experimental. The first recipient was close to death and didn't expect to live more than a few months, nonetheless, medical trials will continue.
