The objectives of the paper are to present a design of a test rig for conducting the study on anastomotic proximal model as well as the preliminary velocity vector measurements of the anastomotic proximal sections of varying angles using Particle Image Velocimetry (PIV) technique. In the study, the test sections are modeled as rigid tubes assuming that synthetic graft and diseased arteries are expected to be relatively stiff. The anastomotic test models are designed in actual size and the fluid used is comparable to the mechanical properties of the blood in both viscosity and density. It is hope that with the investigation, an interposition sleeve for joining the aorta to vein graft and vein graft to the coronary artery in a bypass operation can be properly designed and constructed. The sleeve will maintain an adequate arterial contour and reduce the chances of postoperative symptoms like endarterectomy, carotid aneurysm and kinks problems.
