BIOMECHANICAL ASPECTS OF DEVELOPMENT OF ADVANCED POLYMER PROSTHESIS OF HEART VALVE

Abstract
The biocompatibility of cardioimplants based on the natural and synthetic materials has been discussed in the paper. The biomechanical characteristics of artificial heart valve with elastic leaflets made of homogeneous isotropic and directly reinforced anisotropic polymer materials have been studied. It was shown that bending fatigue strength of leaflets in a range of 108-109 cycles is most important criteria of this structure durability. The finite element calculations of stress-strained state of aortic prosthesis in systolic phase of heart cycle have been done. Modeling of deformational characteristics and analysis of fatigue strength allows proposing the prosthesis with leaflets made of directly reinforced anisotropic polymer composite based on polyurethane matrix.
