The flow diversion technique with the use of embolisation devices placed in the parent artery is a new approach to treat intracranial aneurysms – especially fusiform and large ones with a wide neck.
These devices have a high vessel wall coverage and the ability to change haemodynamic forces and vectors in the segment bearing the aneurysm.
Long lesions can now be treated by a single DERIVO® instead of using several devices in a telescoping technique.
