Abstract

Cardiovascular diseases area major cause of death in the world and are closely related to the dynamics of the blood and arterial wall mechanics. Not only in the cardiovascular system, but also in the whole body system, the heart is the most important organ, if the blood vessels of the heart are blocked heart function will be impaired. Effective solutions to resolve blockage of coronary is the bypass surgery in which are placement vessel for the blood supply to the heart. So studying the behavior of the vessels that are used for the bypass is important. The goal of this study is the investigation of the mechanical behavior of saphenous vein by using the tensile biaxial tests. Eight human saphenous samples were obtainedand the planar biaxial tests were performed on the tissue specimens by applying simultaneous loads along the circumferential and longitudinal directions. Then the measured data were fitted into the four-parameter Fung-type model and also to the five-parameter MOONEY-RIVLIN MODEL, this could be used in finite element packages for numerical analysis. The specimens were stiffer in the longitudinal than in the circumferential direction. The specimens showed some degree of anisotropy.
