Description

The purpose of this research was to provide the artificial heart design information necessary for the proper development of an implantable nuclear power supply for the artificial heart. A Kwan-Gett hemispherical artificial heant made of silicone rubber was attached to a mock circulation instrumented with pressure, volume and fiow transducers and measurements made of power input to the artificial heant at various locations, source of power losses and efficiencies of the artificial heart under a variety of pumping conditions, volumetric efficiency, pressure required to move the diaphragm of the artificial heat, required motion of the heant diaphragm and pumping characteristics ... continued below

The in vitro measurements have been verified by in vivo experiments in calves. The preliminary design of a pumping chamber for the nuclear powered heart has been completed. (auth)
