Artificial Heart- New hope for heart patients

About 4,000 people in the US are waiting for heart transplantation. And on average, it takes about six months to get one, during which some patients will die.

So the researchers have been trying to create an artificial heart for decades, which can be implanted permanently. But a manufacture that is incredibly difficult for a long time to imitate a real heart or without infection or blood clots. One problem is that there are more parts, and things can be wrong.

In order to solve the problem, Sanjeev Kaul and his team are developing an artificial heart with an extremely simple design at Ongon Health and Science University - there are only one walking pieces in the valve. He believes that this can be the first tool that can end a person's life.

Originally designed by Richard Wampler, the artificial heart of the OHSU creates a blood stream that mimics the natural pulse. It replaces the two lower chambers, the ventricles of the human heart, in which there is a titanium tube with a hollow rod which further moves further. This back and forth motion pushes blood to the lungs so that it can remove the oxygen and then transfer oxygenated blood through the remaining body.

This design will remove previous artificial heart borders.

The artificial heart of the OSHU team does not have a moving piece and no valves.
Prior to the American Food and Drug Administration in 2006, Artificial Hearts, Abiocar received limited approval. It was implanted in only 15 people and is no longer available. It was too big for the size of the grapes, to fit in children and many women.

Only one artificial heart produced by Sychardia, currently available in the US. This means having a temporary fix, while patients wait for heart transplantation. For this, people need to take an external air compressor in a backpack which pumps the implanted artificial heart from outside.

Other companies like Cleveland Heart and French firm Carmat are trying to create a completely artificial heart. Last year, Swiss researchers reported that they had a 3-D-printed one, but it started to decline after only 45 minutes.

Kaul and his team tested the initial prototype of their artificial heart in cows and did not notice any problems or side effects. After this, they are planning to test a small version-which is enough to fit in children, that is about 10 months old as a sheep.

"If it works for a long time, we think we will be able to put it in people," he says.

The device may be available for patients five years or even for the earliest.

The artificial heart of the OHSU will probably need to be charged with a small, hand-held battery pack outside the body. But it is hoped that a small, more efficient battery can be put finally under the skin and can be recharged from the outside.
