I’d be friends with the sparrows and the boys who shoot the arrows, if I only had a heart...well, suppose the wizard wouldn’t give me a heart when we got there? Heart failure alone kills a shocking 300,000 Americans each year, and heart diseases wipes out at least 600,000, making it the leading cause of death in America. The amount of heart disease and death by heart failure is only increasing.Different types of artificial hearts such as the Syncardia, Cardio West, and Abio Cor artificial heart systems have varying structures, but are all based on a pump model hat assists the contraction of ventricles.
When the diaphragm in the ventricle expands, it provides enough pressure to eject blood.
A vacuum supplied by a pneumatic power source pulls the diaphragm down, allowing blood to fill the ventricle.
(3) Thanks to the collaboration of engineers from various fields, the artificial heart has so far been a success in saving lives.
One of the first steps in creating an artificial heart is the design process.
Medical engineers have been attempting to create a replacement for the heart since 1911.
One of the greatest developments in medical technology in the past century was the invention of the Total Artificial Heart by Willem Kolff, one of his most prolific inventions out of his other revolutionary artificial organ devices.
A special coating of titanium is used on blood contacting surfaces, allowing blood cells to adhere to the metal, creating a living surface that mimics a real heart.
The diaphragm within the pump is made from polyurethane, an easily modifiable, chemical-resistant material, also chosen because blood can easily adhere to its surface.
Ideally, the materials in an artificial heart should be similar to those of an actual heart while also maintaining durability and flexibility. The basic framework of the artificial heart is often composed of plastic, titanium, polyurethane, and even animal parts such as heart valves from pigs.
An alloy, which is a metallic mixture, primarilycomposed of titanium, aluminum, and vanadium, is used for the pump, motor, and other metallic parts of the heart.
