Abstract
A vasoocclusive device in the form of a coil for placement in the vasculature of an animal to form thrombus in a selected site such as an aneurysm or AVM. The device involves a primary coil form having thrombogenic fibers placed on the coil in a specified fashion. The coil will pass through the lumen of a vascular catheter in the primary coil form and evolve into a convoluted or complex secondary form when ejected from the catheter's distal end. The fibers are attached to the coil and cooperate with the coil so that upon ejection from the catheter, the convoluted coil forms a shape in which the central region or secondary coil form center that contains the majority of these fibers.
