METHOD AND DEVICE FOR TREATING INTRACRANIAL VASCULAR ANEURYSMS
UCLA Technology Available For Licensing

Strokes are the most common life-threatening neurological disease, and are the third leading cause of death in developed countries after heart disease and cancer. Approximately 6-8 percent of all strokes results from non-traumatic subarachnoid hemorrhage, a condition where blood leaks from the cerebral vasculature into the subarachnoid space. About 8 percent of subarachnoid hemorrhages result from rupture of an intracranial aneurysm.

Ruptured intracranial aneurysms are associated with a high rate of mortality. Approximately 15% of the patients die soon after the initial rupture. An additional 20 to 30% of the patients die during the first 2 weeks following the initial rupture. Rebleeding is one of the major causes of death in the patients who survive the initial hemorrhage. In addition to the high mortality rate associated with ruptured intracranial aneurysms, there is also a high morbidity rate among patients who survive the rupture long term. Almost two-thirds of patients well enough to be discharged home after surgical obliteration of the aneurysm have a residual neurological deficit.

Inventors at UCLA have developed a device, and a method, for the therapeutic management of intracranial vascular aneurysms. This technology involves the use of intravascular catheters that can directly image the aneurysm, and can occlude the entire lumen of the aneurysm sac using liquid sealing agents. The intracranial catheters are designed in various configurations so that they can be used to treat aneurysms regardless of their neck size, and their location within the intracranial vascular system.
