In 2019, data from a study by Dr. Scott Trerotola, Head of Interventional Radiology at the University of Pennsylvania, demonstrated that polymeric fiber coils significantly reduce the number of embolization coils used to achieve acute arterial occlusion more effectively compared to bare metal coils. An average of 3.2 non-fibrous waves and an average of 1.3 fibrous coils are required to achieve arterial occlusion of similar size. It has also been shown that fibrous coils create a safer occlusion over time.
