[Power units of implanted artificial heart and assisted circulation system]. / Energeticheskie bloki, ispol'zuemye v implantiruemom iskusstvennom serdtse i sistemakh vspomogatel'nogo krovoobrashcheniia

The existing and presently planned systems of power supply for an artificially implanted heart and assisted circulation devices are reviewed. A comparative analysis as to their conformability to biological, functional and technical demands placed on the implanted systems is given. In an implanted artificial heart and assisted circulation systems most promising is shown to be the use of nuclear fuel as a source of power and as converters -- that of thermal engines with gas and steam cycle.

[Components of an implanted artificial heart and the medico-technical requirements]. / Sostavnye elementy implantiruemogo iskusstvennogo serdtsa i pred'iavliaemye k nim mediko-tekhnicheskie trebovaniia

The task of designing and providing power supply for an implanted artificial heart (AH) is a many-sided complex problem that includes a number of medico-biological, technical, physical, power-supply and other factors. The analysis of the AH components and the mentioned basic medico-technical requirements permits it to outline the ways and means for a rational solution of this complicated problem. The greatest attention is paid to the analysis of and future prospects for the use of different power sources and methods of power conversion.
