Abstract

See full text

A ventricular assist device for documenting compressive forces on the right and left ventricular surface of a heart in terms of pressure reactions transmitted from fluid contents in sacs adjacent to these ventricular surfaces to apparatus for displaying the reactions, and a method of monitoring these pressure forces and their effects on the ventricular surfaces for circulating the blood from the ventricular blood pools into the right and left arterial systems.
