The advanced flexibility of the coil realizes the Loop-in-Loop coil-folding feature which enables coil-packing without remaining gap space.

2-4ES (ø2mm x 4 cm) TypeR tightly packed in a 2 mm aneurysmal model. The advanced flexibility of the coil realizes the Loop-in-Loop coil-folding feature where small loops are formed in surrounding exterior loops.

Waving Inner Wire Technology enables smooth coil-folding till the end of the coil.

Waving Inner Wire (made of 10 μm-twined platinum wires) enables smooth coil-folding till the end of the coil even in a small space.
