Invent: To produce or contrive something previously unknown by the use of ingenuity or imagination. (Webster)

Owen H. Wangensteen, MD, set the stage for investigative thought and surgical research in 1931 with his invention of the nasogastric suction apparatus for the care of patients with bowel obstruction [1]. When Dr Wangensteen was advised to apply for a patent on his suction apparatus he declined. Doctor Wangensteen believed that it was wrong "to profit from his invention." (Sarah Wangensteen, Dr Wangensteen’s wife, recalled his response in conversations with Elaine Challacombe, curator of the Wangensteen Historical Library.)

Doctor Wangensteen continuously initiated innovative ideas in surgical research. In the late 1950s he developed an apparatus for gastric mucosal freezing for the treatment of duodenal ulcers. Doctor Wangensteen expected all of his students to have a strong interest in surgical physiology and research.

In the late 1940s the pediatric cardiology department of the university saw patients from a wide referral area in the Midwest. Doctors Paul Adams and Raymond Anderson directed that department. They saw many patients with inoperable intracardiac defects and for which they had inadequate solutions. Because of this large backlog of children with inoperable intracardiac congenital heart defects, Drs Adams and Anderson encouraged the surgery department to find methods for the correction of these defects.

After World War II cardiovascular surgical problems became a new challenge and attracted surgeons’ attention in many of the world’s surgical centers. In 1945 Dr Wangensteen suggested to a surgical staff member, Dr Clarence Dennis, that Dr Dennis might consider the development of a pump-oxygenator system to aid body support during cardiovascular surgical repairs [2]. Doctor Dennis and his team began research in 1947 to develop a rotating screen disc oxygenator, which was used clinically in April 1951. Doctor Dennis became Chairman . . .
