Abstract

IN THE past several years a number of investigators interested in intracardiac surgery have produced pumps to serve as mechanical hearts. Much of this work has been stimulated by the efforts of Gibbon,1 Dennis and associates,2 and others to produce an artificial heart-lung system and by the studies of Sewell and Glenn,3 and others,4 in which a pump is used to bypass parts of the heart. We became interested in this field in 1949, and thought that a small compact pump could be produced by using the diaphragm principle. This report describes the resulting pump and indicates how it operates when used to duplicate the right heart bypass operation described by Sewell and Glenn.3 Additional experience with this pump when used to bypass the left heart is reported elsewhere.5
