摘要：
A shape memory coiling device (5) for occluding a vessel or other vascular target includes a shape memory polymer material. The shape memory material is formed in a formation state as a plurality of coiled members (10) and then constrained in a pre-deployed state as a plurality of elongate members (10) configured for delivery through a delivery device wherein the plurality of elongate members (10) are aligned axially with respect to each other and the delivery device (20). The shape memory material may be formed in an intra-deployed state such that at least one of the plurality of elongate members (10) will anchor the device (5) before filling the vascular target and becoming a coiled member. The shape memory material is formed in a deployed state as a plurality of coiled members (10). In some embodiments, the vascular target is an aneurysm.
