Abstract:
A method for embolizing a target vascular site having a defined volume, comprising the steps of:(a) passing a microcatheter intravascularly so that its distal end is introduced into a target vascular site;(b) passing a vaso-occlusive device through the microcatheter into the target vascular site so that the vaso-occlusive device assumes a three-dimensional configuration that fills a portion of the volume of the target vascular site;(c) providing a vascular embolization device comprising an expansible embolizing element non-releasably carried on a flexible filamentous carrier;(d) passing the embolization device through the microcatheter so that it emerges from the distal end of the microcatheter into the target vascular site; and(e) expanding the embolizing element in situ substantially to fill remaining volume of the target vascular site while retaining the embolizing element on the carrier.
