采用动脉瘤模型研究弹簧圈栓塞后的填塞密度。导入铂弹簧圈，直至达到最低密度填塞点，这表明存在动脉瘤循环阻断。填塞持续到最大密度点，即突出到载瘤动脉中。计算最小和最大致密填充的体积比（弹簧圈体积/血管体积）。最大致密填充比略高于最小致密比，但小于37%。
Aneurysm models were used to study the density of packing after coil embolization. Platinum coils were introduced until the point of minimally dense packing, indicated by aneurysmal circulatory exclusion. Packing was continued up to the point of maximal density, indicated by protrusion into the parent artery. Volumetric ratios (coil volume/aneurysmal volume) were calculated for minimally and maximally dense packing. Maximally dense packing ratios were a little higher than the minimally dense ratios, but less than 37%.
