For the purpose of optimizing pump turbines installed in pumped storage plants with regard to efficiency, cavitation, and excavation costs, a method of computation has been devised which includes a new system of determining type number and impeller outside diameter. An example employing data applicable to a modern pump turbine—Rodund 2(Austria)—reveals

After years of development and preclinical testing, clinical trials of the MicroMed DeBakey VAD began in November 1998 in Europe and in June 2000 in the United States. As of August 2000, 44 patients in Europe and 3 patients in the United States have undergone implantation with the MicroMed DeBakey VAD.
