notes: label: Description
content: This box contains various parts of St. Jude Artificial heart valves. There are 5 valves, 4 donuts (with no leaflets or Dacron sewing rings), 1 incomplete valve (lacks a leaflet and cloth suture), and 2 individual leaflets. Demo valves are sometimes made of anodized aluminum instead of pyrolytic carbon. The St. Jude Medical (SJM) valve was the first all carbon valve in clinical use. All St. Jude valves would be made with pyrolytic carbon, a material and coating recognized for its biocompatibility, thromboresistance, and durability. It quickly became the 'gold standard' for subsequent valves regardless of their manufacturer. A white Dacron sewing ring surrounds the valve.
label: Description
content: St. Jude Medical was founded by Manuel 'Manny" Villafaña in 1976, in St. Paul, Minnesota, U.S.A. The model for its popular bi-leaflet valve was developed at the University of Minnesota in 1972 by Dr. Demetre Nicoloff (1934-2003). It differed from previous valves because it was made of pyrolytic carbon, a material that was very durable and could last many years in the body. Dr. Jack Bokros, founder of OnX Life Technologies Inc., is the doctor who developed this material. Manny Villafaña is a businessman whose first company was Cardiac Pacemakers, Inc. The first surgical implant with a SJM valve was carried out in October 1977.
