Abstract
The invention provides a vaso-occlusive device having a braid comprising a bioabsorbable or bioactive material placed over and retaining a helical metallic coil. The braid or the coil may have one or more fibrous elements attached. A helical metallic coil comprising one or more attached fibrous elements is also claimed and described. Corresponding methods of making these devices and of treating patients having abnormal blood flow by implanting such devices at a site of abnormal blood flow are also claimed and described.
