The scale properties of a one-dimensional lattice model for the blood vessel with a heterogeneous part (an extended Sakanishi model) have been investigated. In the present study, from the viewpoint of mechanics, a part of the blood vessel, which has the different mechanical properties of the vessel wall, that is, a part of arteriosclerosis, prosthesis and so on, is regarded as the heterogeneous part by a generalization for the one-dimensional lattice model. The stability of the solitary wave is applied in order to obtain the reliable results by the numerical analysis of the pulse wave which propagates through the heterogeneous part in the blood vessel. As a result, we show the behaviors of the pulse wave through the blood vessel with the heterogeneous part under the condition that the scale of the pulse wave, the length of the heterogeneous part and the mechanical properties of the vessel wall are changed.
