Denton Cooley 1960s. He and his colleagues worked on developing new artificial heart valves from 1962 to 1967; during that period, mortality for heart valve transplants fell from 70% to 8%. In 1969, he became the first heart surgeon to implant an artificial heart designed by Domingo Liotta in a man, Haskell Karp, who lived for 65 hours. The next year, in 1970, "he performed the first implantation of an artificial heart in a human when no heart replacement was immediately available." Cooley's interests included basketball, which he played in high school and as a three-year letterman for the UT men's basketball

Although models vary, the common thread among currently available designs is a mechanical constriction mechanism placed around the urethra, and an externally accessible control mechanism allowing the user to relieve the constriction to allow urination. Artificial urinary sphincter surgeries have been performed since being first introduced in the early 1970s. The most commonly used device
