ABSTRACT:
A pump adaptable for use as a human heart includes first and third pump chambers separated from an intermediate second chamber which may house a motor. The chambers are separated by diaphragms which may be alternately driven. A pump is achieved which needs no venting. Each of the first and third chambers can pump blood in operation and can be connected in series or separately to the ventricles of the heart.
