The experiments showed a non-linear relationship between stress and strain in the infantile aorta, the modulus of elasticity of the aortic wall increased with the increase of inner pressure. In the case of anastomosis end-to-end the modulus was almost constant, relevant to the modulus of elasticity of the aorta with the inner pressure 100-120 mmHg. The anastomoses EETE and SFA showed elastic properties closer to native aorta, the stiffness of ETE did not change with the changes in inner pressure.}, journal = {International Journal of Biomedical and Biological Engineering}, volume = {6}, number = {6}, year = {2012}, pages = {198 - 201}, ee = {https://publications.waset.org/pdf/13230}, url = {https://publications.waset.org/vol/66}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 66, 2012}, }
