<p>An artificial heart pump includes first and second opposing leaves (22, 24) having side edges joined in face-to-face relation. First and second housing portions (26, 28) surround outer surfaces of each of the first and second leaves (22, 24). Pressurized fluid is admitted into chambers (32, 33) between the leaves (22, 24) and the housing portions (26, 28) to urge the leaves (22, 24) toward one another to cause a pumping action.</p> |
