Figure 4From: Porous media properties of reticulated shape memory polymer foams and mock embolic coils for aneurysm treatmentPacked MECs in the measuring chamber. Coil lengths of 0.28, 0.47, 0.59 and 0.71 m were randomly packed to achieve packing densities of 11, 16, 23 and 28%, respectively. Packing density (η) was calculated by dividing the volume of the coil by the cylindrical bounding volume of the coil mass.Back to article page
