In the initial stage of endovascular treatment of aneurysms, adhesive liquid embolic agents IBCA, NBCA and non-adhesive embolic agent CAP were used for embolization of intracranial aneurysms, but they are prone to reflux and lead to accidental embolization, so they are no longer used. LavaTM is a new type of non-adhesive embolic material which is composed of EVOH (Ethylene Vinyl Alcohol Copolymer) with suspended micronized Tantalum powder for radiopacity, and DMSO (Dimethyl Sulfoxide) solvent. LavaTM liquid embolic agent has been approved for clinical trials and applications in Europe. It can be solidified and shaped according to the shape of the aneurysm, so that the new endothelium can cover the opening of the aneurysm. LavaTM is a liquid that is injected into the aneurysm for a short time to solidify.
