Abstract: An occlusion device for a vascular or biological lumen includes a plurality of coiling members held together at both the proximal and distal ends by retaining features. A restraining loop can hold coiling members together at a point along a length of the coiling members. The coiling members are delivered simultaneously to form a coil pack to occlude a target location in the lumen. One or more of the coiling members has at least a portion with a larger curl diameter than other coiling members to secure the occlusion device against lumen walls at the target location. The coil members may have different or varying material moduli. The device may be used, for example, for occluding a vessel to block blood flow to an artery supplying blood liver (hepatic artery), kidney (renal artery), spleen (splenic artery) or intestines (mesenteric artery).

Abstract: A delivery apparatus for a lumen occlusion device includes a pusher configured for releasably coupling with and pushing and pulling a proximal end of the occlusion device in a distal or proximal direction and a distal control wire capable of releasably coupling with the distal end and the proximal end of the occlusion device. The control wire may be configured for moving the distal end of the occlusion device in both proximal and distal directions allowing precise simultaneous control of both proximal and distal ends of the occlusion device. Control of both ends provides for placing the occlusion device in tension during delivery through a delivery catheter, thereby reducing delivery forces, achieving greater compaction of the occlusion device in the lumen, and precisely locating both distal and proximal ends of the occlusion device within the lumen.

Abstract: 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.
