- the vessel outer wall support according to the present invention is designed to include an arterial support and a transplanted vein support, and in order to minimize the occurrence of abnormal blood flow of blood vessels flowing from arterial blood to venous blood when the vessel outer wall support anastomoses blood vessels, it is formed in a U shape.
- An anastomotic device was devised, and the curvature was presented and compared according to the angle of the vein junction .

- the pressure burst strength had a certain tendency and increased by about 39% on average (FIG. 14).
- Vein is a biological tissue with hyperelastic properties, and since it does not follow the linear and nonlinear properties of other polymer materials, it recovers elastically and exhibits incompressible behavior even when considerable plastic deformation occurs.
