ABSTRACT:
An artificial heart is made of a pair of substantially seamless, polyurethane rigid outer housings each having a shape approximating the combined outer shape of a natural cardiac ventricle and its associated auricle, with the bases of each of the housings being bonded together. Each of the outer housings includes a flexible bladder contained within the housing and having an expanded shape approximating the shape of the outer housing. This bladder is spaced from the interior surface of each of the housings a predetermined distance and the lower perimeter of the bladder is attached to the respective base. The bladder in each of the housings is attached at a point opposite the base to the interior of the housing, and a provision is made for expanding and collapsing the bladder under the control of fluid supplied to and removed from the region contained within the bladder between the bladder and the base in each housing. Each housing also is provided with one-way input and one-way output check valve openings for connection, respectively, to the veins and arteries which normally return blood to and convey blood from the heart.
