The sideview of the stiff graft model is shown together with the measurement locations. A schematic diagram of the flow circuit is also shown for the proximal model test. The graft pipe is connected to the head reservoir while the artery pipe is connected to the return reservoir. For the proximal model test, the connection of the graft and artery pipes to the reservoirs is reversed.

The graph shows the percentage less the deformations of the ESA models are when compared to the straight artery model (Healthy Artery). Sideview measurements were taken for various axial locations along the host artery of the ESA. The stiff graft (G/A) has a constraining effect on the host artery when compared to the compliant graft (A/A).

More significant fluid dynamic disturbance is evident in the distal junction when compared to normal fully developed flow. The comparisons between the stiff (bold line) graft model profiles and the compliant (dotted line) graft model profiles are less significant.

The proximal end results (top) show the magnitude of the velocity decrease in the compliant model when compared to the stiff model. The distal end results (bottom) show the magnitude of the velocity decrease in the compliant model when compared to the stiff model. It is seen that the differences between the profiles generally lie within 40% with notable exceptions at the distal end. The toe −4.65mm position corresponds to the position of the maximum bulge.

The compliant graft results (top) show the contrast in velocities between the proximal and distal end for the compliant model. The stiff graft results (bottom) show the contrast in velocities between the proximal and distal end for the stiff model. It is seen that the differences between the flows at the proximal and distal ends vary up to 80%. The toe −4.65mm position corresponds to the position of the maximum bulge.
