Abstract
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.
Claims6
In a ventricular assist device to enclose the right and left ventricular surfaces of a heart in a shell having interior flexible membranes attached to the shell to define right and left epicardial sacs adjacent to the ventricular heart myocardium and fluid pressure conduits connected into said sacs, the improvement which comprises:
- (a) separate pressure conduits entering the right and left sacs from the exterior of the device;
- and
- (b) means connected to each of said pressure conduits for generating documentation of the pressure conditions in said sacs.
A method of documenting pressure conditions in a heart assist monitoring device consisting of
- (a) forming right and left epicardial sacs adjacent to the ventricular surfaces of a heart;
- (b) supplying a pressure medium to the sacs at a sufficient value to follow the heart functions;
- and
- (c) monitoring the pressure medium response and visually displaying the value of the pressure so monitored.
