Dr. Sethi invented the first affordable prosthetic foot, which allowed millions of amputees in developing nations to live normal lives. His prosthesis, called the Jaipur foot, has never been patented. It lasts about five years, costs about $30, and is available in 25 countries. Sethi completed his medical degree between India and Britain, and then lectured in surgery at Sawai Man Singh Medical College and Hospital in Jaipur. The Jaipur foot was created after five years of extensive research. He created a foot that is very flexible, allowing the wearer to run, climb, and pedal.
