Multi-fiber shape memory device

A method of manufacturing a shape memory coiling device for occluding a vascular target comprising

• providing a delivery device having a pusher mechanism with a detachment feature;
• providing a shape memory polymer material;
• forming a plurality of coiled members from the shape memory polymer material in a formation state;
• constraining the plurality of coiled members in a pre-deployed state as a plurality of elongate members;
• arranging the plurality of elongate members in parallel;
• providing a retaining loop across an intermediate point of each individual member of the plurality of elongate members;
• folding the plurality of elongate members about the retaining loop to form a proximal end of the plurality of elongate members at the retaining loop and a distal end of the plurality of elongate members at adjacent free ends of the plurality of elongate members;
• and
• operably attaching the proximal end of the plurality of elongate members to the detachment feature of the pusher mechanism of the delivery device.
