Figure 5From: Porous media properties of reticulated shape memory polymer foams and mock embolic coils for aneurysm treatmentPressure gradient versus Darcy velocity of reticulated SMP foams S (A) and L (B). The mechanical reticulation hole density (ζ) has units E + 5 holes/m2. As the hole density increases, the pressure gradient across the samples also decreases for both SMP foam types.Back to article page
