Abstract
R&D of artificial heart has lasted over 50 years, now both rotary and diaphragm pumps can assist the circulation of the patients several years, after solving many technical problems. In rotary heart pumps, the basic technical problems have been the implantability, the compatibility, the pulsatility, the durability, the biventricular assist, the automatic measurement, the bionic control and the thrombus formation. This paper summarizes the author’s contributions in solving these problems and shares the novelties of some Chinese rotary heart pumps with the readers. The energy supply is one of the most important unsolved problems in rotary heart pumps; the present methods either by use of electric wire cross the skin or using transcutaneous inductive system are problematic because they are neither convenient nor reliable.
