Ability to vary the blood flow through the walls for brain aneurysm therapyEnables minimally invasive therapy in the form of blood flow reduction.Added flexibility in redirecting or obstructing blood flow
Technology Application
Intracranial stents for treatment of a cerebral aneurysmEndovascular therapy for a brain aneurysm
Detailed Technology Description
Researchers at UCLA invented a novel dual rotational stent device for the endovascular treatment of cerebral aneurysm without the need for placing coils in the aneurysm lumen. The adjustable and variable strut density pattern of the new stent device allows it to cover the orifice of the aneurysm. This is advantageous for causing blockage of blood flow to the occluding aneurysm while sparing blood flow to perforators or side branches near the aneurysm neck. Specifically, the new compound stent has two main, but separate components: one for being positioned and stabilized in the parent vessel spanning the neck of aneurysm and the other one for controlling the degree of blood flow into the aneurysm.

State Of Development
The inventors are currently creating a prototype and will evaluate its mechanical property in an in vitro and in vivo experimental aneurysm model.
Background
Stents are small metal coils used to open up the clogged artery. Stents help prop the artery open and decrease the chance of it narrowing again. Currently available intracranial stent devices have been developed as an adjunctive technique for coil embolization. These stents are deployed across the neck of a cerebral aneurysm, and the coils placed inside the lumen of the aneurysms preventing the protrusion or escape of these coils. However, all of these stents are designed with a low strut density to allow the placement of coils through them, resulting in difficulties preventing blood flow from getting into aneurysms.
