Current and future valves for blood pumps.
There is a variety of mechanical prosthetic valves that can be applied to blood pumps, and one can be selective about those particular characteristics tailored to each blood pump and its application. These devices have become extremely reliable, particularly since, in the experience of this laboratory, the dp/dt generated in the ventricle of the pneumatically powered artificial heart is successfully lowered. Future modifications of the valves, such as the Medtronic-Hall monostrut valve and the Medtronic-Hall tubular valve, are expected.
