- Fig 1.
Intraaneurysmal pressure measurements of the nontreated aneurysm model (control), after placing two structural coils (2nd coil), after placing six hydrogel-coated coils (8th coil), and for the complete filling (14th coil). Measurements were normalized with the measured pressure at peak systole for the control case, PS,C. The slight difference between the curves remains within the measurement error (±2 mmHg).
- Fig 2.
Resulting velocity field after complete filling at the four representative points of the cardiac cycle: at the acceleration stage of the systole, A; deceleration stage of the systole, B; peak diastole, C; and resting period, D. The flow in the parent artery is shown to be reestablished.
