Artificial heart by an immunosuppressive drug complication. The original prototype of Liotta-Cooley artificial heart used in this historic operation is prominently displayed in the Smithsonian Institution's National Museum of American History "Treasures of American History" exhibit in Washington, D.C. The first clinical use of an artificial heart designed for permanent implantation rather than a bridge to transplant occurred in 1982 at the University of Utah. Artificial kidney pioneer Willem Johan Kolff started the Utah artificial organs program in 1967. There, physician-engineer Clifford Kwan-Gett invented two components of an integrated pneumatic artificial heart system: a ventricle with hemispherical diaphragms that did not crush
Artificial urinary sphincter Artificial urinary sphincter An artificial urinary sphincter (AUS) is an implanted device to treat moderate to severe stress urinary incontinence, most commonly in men. The AUS is designed to supplement the function of the natural urinary sphincter that restricts urine flow out of the bladder. 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
