When the Texan Craig Lewis is 55 years old, he set a very bad diagnosis. It turned out that he was ill rare disease - amyloidosis. It is a violation of protein metabolism, resulting in tissue accumulated abnormal proteins that remove organs from damage.
First of all heart disease struck Craig. And judging by the state of his life he had only a few days. The situation was aggravated by the fact that Mr Lewis could not be transplanted donor heart. After all, soon a new heart also would be affected.
Then the doctor from the Texas Heart Institute Billy Cohn and Bud Frazier was offered to the patient to replace an artificial heart with an innovative mechanism.
If all the previous models of the artificial heart imitated the work of this body, and the Con Fraser proposed replacing the complex system of valves miniature turbines. They provide a uniform circulation, without jerks. So listen to the pulse of a man with an artificial heart is not possible.
"The main task of the heart - is to ensure the circulation of blood throughout the body. The human body is designed so that the heart can do so only with the aid of muscle contraction. But this does not mean that the artificial heart has to work as well. For example, birds are forced to fly to flap their wings. But the development of aviation has shown that it is much easier and more efficient to make a fixed-wing aircraft, "- said Billy Cohn.
Earlier, a similar artificial heart has already been successfully tried out in calves. And now Craig Lewis gave his consent to the first person that mechanism.
Mechanical heart transplant was successful. And two days after surgery, Craig was able to climb on the bed. A week later, he was able to have their own back on its feet!
"For a long time I did not feel as good as it is now"- he said. Although quite strange not to probe at his pulse, but everything else was just fine. "I am sure that for the invention has a great future. I am infinitely happy that there are such bright minds as Cohn and Frazier in the world" - said the brave Texan.
Unfortunately, only a heart transplant defer death of Craig. It continued amyloidosis affect other vital organs. And two months later, he passed away due to liver problems. But his example showed that the artificial heart with a continuous blood circulation can be a real salvation for people with severe cardio illnesses.
Yes, modern medicine making wonders! And if you are impressed with this invention, then tell your friends about it.
