Oregon University of Health and Science engaged in the development of Dr. Richard Vampel to improve his project of permanent artificial heart. This is the only mechanical heart that has received permission to use in the US, even if only for the period of waiting for the donor organ.
It looks like a man-made heart as an engine, it is essentially the same. This is a set of cylinders made of titanium alloy, inside of which a pair of pistons moves on hydrodynamic bearings. The movement is as simple as possible, back and forth, at a set frequency, in the tube interruptions are covered by valves. There is nothing to break, get stuck or turn, the probability of device failure is minimized to the limit.
The artificial heart simulates the operation of the two lower chambers of the present organ and instead of a constant blood flow provides a double cycle of blood flow, first through the lungs, then through the patient's body. This should reduce the pressure on the vessels, reduce the risk of stroke and internal bleeding.
An energy source for the heart while external, a battery for wearing on the belt, combined with a control panel. With the advent of new batteries, there is a chance to make it more compact and implant directly into the human body. Scientists have successfully carried out experiments on cows and sheep and are now engaged in designing a model that can be installed already by a person.js.src = “&version=v2.8”; 'script', 'facebook-jssdk'));
