A non-bioabsorbable, metal device intended to be implanted in a non-neurovascular blood vessel, permanently or long-term, to occlude blood flow typically for treatment of an aneurysm, tumour (e.g., nephroma, hepatoma, uterine fibroids), and/or arteriovenous malformation (AVM). It is in the form of an expandable metal scaffold, which once expanded is intended to induce thrombosis and create a blockage; it is typically supplied with instruments dedicated to implantation. This device is not intended to be used in intracranial arteries or for other neurovascular applications.
