Objective:Getting the ascending aorta out of Wista rats, and measuring the horizontal and vertical artery elastic parameters. Analyzing the material performance, and offering data for biomechanical finite element analysis and the artificial vascular materials design. Methods:Wista rats were divided into two groups, one for measuring vascular transverse elastic parameters and the other for longitudinal elastic parameters. Get the ascending aorta, use the artery folder to fix to the arteries transversely and longitudinally, the arteries folder will be fixed in a dedicated folder on the biological extensometer. Results: The records of measured data, the elastic parameters of horizontal and vertical elastic parameters of each 9. Calculate the elastic modulus of each group, while carry out the statistical analysis. Conclusion:The test uses direct method for measuring the rat aorta vascular elastic parameters. Getting the transverse elastic modulus is (0.03206±0.00062) Mpa; the longitudinal elastic modulus is (1.515267± 0.19968) Mpa. Use obtained the elastic modulus of blood vessels, and then added them to the established geometric model of the ascending aorta, carry out the finite element analysis of the ascending aorta, and build the initial physical model.
