Physician Charles Dotter's medical celebrity came with his development of angioplasty as a means of helping heart patients without the necessity of surgery.
Working with Melvin Judkins, he introduced this innovation in 1964, using catheters to improve the flow of blood by widening partially blocked arteries. At first, the procedure was termed "dottering."
Dotter's innovation caught on more readily in Europe than in the United States, where at first doctors did more dithering than dottering.
Dotter worked for years at the University of Oregon Medical School. He died in 1985.
