Abstract

A new jellyfish valve was designed with a new concept. The valve has a simple structure: The center of a thin circular polymer membrane is fixed on a base plate, which has many holes or slits to reduce flow resistance and help hold of the membrane during the diastolic phase. In a mock circulation study, the valve displayed performance similar to the Bjork-Shiley valve. The small amount of regurgitant flow was observed at valve closure, in comparison with the Bjork-Shiley valve. This jellyfish valve is promising for use in a AH blood pump.
