How Peripheral Embolic Coil Design Differences Affect Embolic Efficacy1

PRE-CLINICAL STUDY DATA
Interlock coils—the only coils with PET fibers—occluded up to 45% faster than competitors. New pre-clinical data showed that coils with PET multifilament fibers are more occlusive than coils with nylon/PGLA monofilament fibers, or those with no fiber or hydrogel.
The study showed that when using coils of similar lengths, Interlock used the least amount of coils to achieve total occlusion than any other brand in the study.
Faster occlusion and fewer coils add up to greater value. On average, this study showed that Interlock 18 offered the lowest cost per procedure.
Paired arteries (3) were occluded in each swine, and 6 sets were occluded for each group. Occlusion efficacy assessed by the number of coils used, unit length of coils and the amount of time required for complete embolization. Results were normalized for animals and vessel type differences, by applying a statistical-general linear model.
