A Total Artificial Heart (TAH), as shown in Figure 2, is where surgeons replace the left and right ventricles with either a biocompatible plastic or another man-made material (Laurenson, 2011). The biocompatible plastic that is typically used is called, “Angioflex”, and it is composed up of special polyurethane and titanium (Avula, 2013).
The heart has four chambers. Blood is pumped through the chambers, aided by four heart valves- mitral, tricuspid, aortic and pulmonary. The valves open and close to let the blood flow in only one direction. Each valve has a set of flaps. When working properly, the heart valves open and close fully. An artificial heart valve is a device implanted in.
In the literature, there are some applications of mathematical and physical analog models of total artificial heart (TAH), a baroreceptor model, a state-space model, an electromechanical.
Artificial heart with 1 hour charging providing human to do theirs chores.how the wave energy generated in an artificial heart to do communication is discussed by the author Bohang and et.al(8) in his reaserch paper while how the blood in artificial heart pump and circulate throughout the body of human is given by Min.ByoungG and et.al(8).
The following research papers have been published by members of Stanford's Heart Transplant Team. Clinical research studies. Clinical research studies are designed to answer specific questions, sometimes about a new drug or medical device's safety and effectiveness. Research studies may be observational studies or clinical trials.
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 case heart transplantation is impossible.Although other similar inventions preceded it from the late 1940s, the first artificial heart to be successfully implanted in a human was the Jarvik-7 in 1982, designed by a team.
Artificial heart valves are engineered devices used for replacing diseased or damaged natural valves of the heart. Most commonly used for replacement are mechanical heart valves and biological.

Artificial heart valves can be biological or mechanical. Biological valves are made of human or animal tissue (cow and pig hearts are often used) and usually have a shorter life span than mechanical valves. Mechanical valves, however, require the patient to take anti-coagulant medication continually to prevent blood clots (source: HealthGrades.
