摘要
This invention is a device for occluding an aneurysm comprising: a rotating member that is inserted into, and then rotated within, the aneurysm; and one or more fill members that are dispensed outwards from one or more openings in the rotating member toward the aneurysm walls. Coordination of the rate of rotation of the rotating member with the rate at which the one or more fill members are dispensed from the rotating member can create a densely-packed spiraling mass that fills a higher percentage of the volume of the aneurysm interior than is possible with deployment of coils in the less-directed, relatively-random manner used in the prior art.
