Abstract

Abstract

Using finite elemcnt method,this paper has analyzed the blood-mechanical heart valve interaction system subjected to a step pressure when the vaiue is at closing position.As demonstrated in the present stud),,in such conditions mechanical values made of pyrolytic carbon,Ti alloy,Co-Cr alloy and ceramics tend to be very stiff which result in high impinging pressure.The impinging pressure acted on the value of the blood-valve sytem can be reduced by decreasing the elastic modulus of the mechanical value.
