Dick Sarns, founder of NuStep and designer of the heart-lung machine that revolutionized cardiac bypass surgery from the 1960s onward, has retired. Having celebrated his 91st birthday back in June and done more for medical device innovation in Ann Arbor than perhaps any other human being, Sarns has more than earned such a respite. I hope you will join me in wishing him all the best, he has given us plenty of his.
