An embolization member (10) and a method for fabricating it are disclosed. The embolization member (10) includes a tubular first helical member (100) comprising a lumen (110), a second helical member (120) sleeved over an outer surface of the first helical member (100) and a securing member (170) at least partially disposed within the lumen (110) of the first helical member (100). The first helical member (100) includes a radiopaque material, and the second helical member (120) includes a bioabsorbable material. The securing member (170) is coupled at opposite ends thereof to respective opposite ends of the second helical member (120), so as to secure the first helical member (100) to the second helical member (120). The securing member (170) incorporated in the double-layer structure of the embolization member (10) not only imparts degradability to the embolization member (10), which can mitigate a possible mass effect that it may exert, but also enable it to maintain good structural stability within an aneurysm.
