Kolff’s determination to save lives led him to move to Kampen to continue his work independently rather than under Nazi supervision during the German occupation. It was in this period that he developed a crude version of his dialysis machine. His breakthrough design eventually reached researchers in Britain, Canada, and the United States, revolutionizing renal treatment. In 1950, Kolff emigrated to the United States, joining the Cleveland Clinic Foundation. Here, he delved into cardiovascular research, where he and a student designed a successful artificial heart-lung machine, a cornerstone for open-heart surgery. In 1961, Kolff invented the intra-aortic balloon pump, an essential tool for assisting circulation during heart attacks.
Kolff’s most ambitious project was the creation of an artificial heart. In 1957, he implanted one in a dog, which survived for ninety minutes, marking a significant milestone in medical history. In 1967, Kolff moved to the University of Utah, where he served as the director of the Institute for Biomedical Engineering and the head of the Division of Artificial Organs. His team focused on developing new prostheses and artificial organs, pushing the boundaries of medical technology.
A strong advocate for home dialysis, Kolff's vision led to the development of the wearable artificial kidney in 1975, making dialysis more accessible and manageable for patients. In 1982, Kolff achieved another remarkable feat when he and his team performed the first human heart transplant using an artificial heart. The recipient, Dr. Barney Clark, lived for 112 days with an aluminum and plastic heart, demonstrating the potential of artificial organs in extending human life.
Kolff's legacy extends beyond his inventions; his work laid the foundation for modern biomedical engineering and prosthetics. His relentless pursuit of innovation and his contributions to medical science have saved countless lives and continue to inspire advancements in the field. Kolff passed away on February 11, 2009, but his pioneering spirit and remarkable achievements endure, marking him as a true visionary in medical history.
