ABSTRACT:
This is a device for occluding a space within the body, and particularly, it is useful as a vaso-occlusive device. In particular, it typically comprises a metallic core or core member, and two polymeric conjuncts, often polymeric members, of differing thrombogenicity. Typically, the core member will comprise a metallic helically-wound coil; the first polymeric member and second polymeric member will be fibrous materials woven into a braid. These devices may be placed at the desired site within a mammal to facilitate the formation of an occlusion. The inventive device has been found to promote the formation of scar tissue, healing tissue, or neocapillaries in vascular occlusions made by the device.
