An artificial heart is a device that replaces the heart.Artificial hearts are typically used as a bridge to heart transplantation, but ongoing research aims to develop a device that could permanently replace the heart when a transplant—whether from a deceased human or, experimentally, from a genetically engineered pig—is unavailable or not viable.
An artificial heart valve is a one-way valve implanted into a person's heart to replace a heart valve that is not functioning properly (valvular heart disease).Artificial heart valves can be separated into three broad classes: mechanical heart valves, bioprosthetic tissue valves and engineered tissue valves.
The Björk–Shiley valve is a mechanical artificial heart valve. The valve was co-invented by American engineer Donald Shiley and Swedish heart surgeon Viking Björk. Beginning in 1971, it has been used to replace aortic valves and mitral valves. It was the first successful tilting-disc valve.
A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [ 3 ] thus regulating the function of the electrical conduction system of the heart .
Willem Johan "Pim" Kolff (February 14, 1911 – February 11, 2009) was a pioneer of hemodialysis, artificial heart, as well as in the entire field of artificial organs. Willem was a member of the Kolff family, an old Dutch patrician family. He made his major discoveries in the field of dialysis for kidney failure during the Second World War. He ...
Artificial heart maker Carmat on Monday secured a 7 million euro ($7.4 million) lifeline to survive an imminent cash crunch, but the deal left questions over future support from co-founder Airbus ...
AbioCor was a total artificial heart (TAH) developed by the Massachusetts-based company AbioMed. It was fully implantable within a patient, due to a combination of advances in miniaturization, biosensors, plastics and energy transfer. The AbioCor ran on a rechargeable source of power.
The pericardial heart valve was invented by Marian Ionescu, a British surgeon working at the General Infirmary in Leeds, England. [1] He created this artificial bioprosthetic heart valve as a three-cusp structure made of chemically treated bovine pericardium attached to a Dacron cloth-covered titanium frame.
