Activatable bioactive vascular occlusive device comprising fibers

摘要

A vascular occlusive device, such as an embolic coil (10), having thrombogenic fibers (19) extending from the coil and having an outer barrier (22) which encapsulates and flattens the fibers along the sides of the embolic coil for preventing activation of the coil until the outer barrier has been dissolved, or removed, from the embolic coil. <IMAGE>
