Abstract
A practical model of jellyfish valve which can be incorpolated into an artificial heart blood pump without seam was designed and fabricated. In-vitro experiment revealed that the valve had superior performances to B-S valve at the points of flow resistance, regurgitation during the valve closure and leakage after the valve closure. Durability test was cleared over 8 months. Essentially, no thrombus was formed around the valve in in-vivo experiments without anticoagulant. The chronic implantation of this valve into the goats as a TAH, revealed an amazing improvement of oathophysiological abnormalities which were always observed in TAH animals.
