In 1955, surgeons at the University of Minnesota operated on 5 patients for open heart surgery using the method of continuous arterial perfusion.

Research showed that when deoxygenated (venous blood) was warmed at 45 degrees Celcius for 15…

The prototype transistorized battery-operated pacemaker was invented by Earl Bakken in 1957.

In 1961, Nazih Zuhdi, a medical fellow in surgery at the University of Minnesota from 1956-1957, introduced hemodilution to open heart surgery. By diluting the blood by priming the pump-oxygenator apparatus with a 5% dextrose water solution, it…

The discovery of methods for open heart surgery would not have been possible without first performing research with canines in the laboratory.

By 1958, Medtronic, Inc. manufactured a commercial model of the 1957 prototype devised by Earl Bakken for C. Walton Lillehei at the University of Minnesota. The "5800" came with a cloth strap and pouch for patients to wear with ease.

The azygos vein is a blood vessel that carries a small amount of deoxygenated blood from the body into the right side of the heart. The vein acts as an alternative path for blood flow when the main blood vessel carriers, the superior and inferior…
