Med. Devices. 2011;5(4): doi: / Figure Legend: Volume renderings of the baseline and proximal bifurcation CTA data sets used in this study are depicted. The proximal bifurcation device was anchored in the aneurysm sac with polymer, thus, masking its double lumen design in the figure.

Med. Devices. 2011;5(4): doi: / Figure Legend: The workflow for virtual intervention begins by isolating the aneurysm region and creating centerlines. The centerlines are then used to extend tubular endograft geometry and joined with a bifurcated section.

Med. Devices. 2011;5(4): doi: / Figure Legend: Four designs (baseline, proximal bifurcation, mid bifurcation, and distal bifurcation) were constructed for each of the four patient anatomies in this study and are pictured above. The three endograft geometries are highlighted in black for each intervention model.

Med. Devices. 2011;5(4): doi: / Figure Legend: Pressure waveforms (solid line) at the inlet were calculated for each patient anatomy. The measured systolic (dashed line) and diastolic (dotted line) patient blood pressures are also shown. There was no difference in the inlet blood pressure for a given patient anatomy across the four different models (baseline, proximal bifurcation, mid bifurcation, and distal bifurcation). The maximums and minimums of the pressure waveform (solid line) were within 5% of the measured systolic (dashed line) and diastolic (dotted line) blood pressure values, respectively.

Med. Devices. 2011;5(4): doi: / Figure Legend: The total curvature of each device design is plotted versus the total displacement force acting on each device. The three data points for each patient represent the three device designs examined in this study. The correlation coefficient (R2) is listed for each patient.

Med. Devices. 2011;5(4): doi: / Figure Legend: The total endograft surface area (mm2) in all three device designs is plotted versus the total force acting on the endograft. The correlation coefficient (R2) is listed for each patient.
