Figure Legend:
The experimental setup used in the study. 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.

Topview of junction illustrating bulging from 0mmHgto140mmHg (top) with graphical results of the top view deformations for the compliant graft model (Artery/Artery) and the stiff graft model (Graft/Artery) at the toe and 4.65mm from the toe (within the junction) which corresponds to the location of maximum displacement.

Figure Legend:
Sideview illustrating constrained expansion of artery bed from 0mmHgto140mmHg (top). 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).

Figure Legend:
Quantitative LDA results for the center-plane measurements in the proximal (top) and distal junctions (bottom). 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.

Figure Legend:
Percentage difference plots of results of hemodynamic investigations for data across the artery. 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.

Figure Legend:
Percentage difference plots of results of hemodynamic investigations for data across the artery. 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.
