The embolization detachable coil consists of platinum-tungsten alloy coil, 304V stainless steel guidewire. The guidewire is coated with a Teflon insulation layer on the outer surface of its proximal segement.

3D coil is a complex coil that is used as initial scaffold for treating intracranial aneurysm or lesion. Single-diameter and dual-diameter coils are helical coils that can be used to provide further filling of the aneurysm or lesion after the to initial scaffold has been formed by the complex coils , or used separately for the treatment of embolized aneurysm.
