Lava-18 Liquid Embolic System

The liquid embolic system is an interventional endovascular therapy for the treatment of cerebrovascular malformations. Cerebrovascular malformation refers to a group of benign or malignant neurovascular abnormalities that can lead to intracranial hemorrhage, cerebral infarction, cerebral ischemia and other diseases. The liquid embolization system is a medical device administered through simple intravascular insertion, which embolizes abnormal cerebral blood vessels by injecting a special fluid material. The fluid material forms a controlled tissue embolism within blood vessels, which can lessen the impact of cerebrovascular malformations on patients. Lava-18 is recommended used when feeding pedicle injections will be conducted close to the nidus. A DMSO compatible delivery micro catheter that is indicated for use in the neurovasculature is used to access the embolization site. Lava liquid embolic agent is a non‐adhesive liquid embolic agent system comprised of EVOH (ethylene vinyl alcohol) copolymer dissolved in DMSO (dimethyl sulfoxide), and suspended micronized tantalum powder to provide contrast for visualization under fluoroscopy.
