Abstract
This invention is a vasoocclusive device. It is placed in the vasculature of an animal to form thrombus in a selected site such as an aneurysm or AVM. The device uses a central coil having thrombogenic fibers placed on the coil in a specified fashion. The coil will pass through the lumen of a vascular catheter and form a convolution 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 contains the majority of these fibers.
