Patent ID: 11911302

Abstract:
A flow diverter device is used to redirect the blood flow inside the cerebral blood vessels and for the reduction of blood flow to the aneurysm, hence preventing the chance of aneurysm rupture as well as promoting the healing of the aneurysm. The novel design of the device, using a set of thicker wires, provides high kink resistance and radial strength. Two patterns of inter-braiding the thicker set of wires with the finer braid are disclosed, one having a checker-board and the other a ring structure. Both patterns are highly kink resistant with the checker-board design providing minimal loss in flexibility, whereas the ring design provides greater radial strength. The device could be made of super elastic materials like Nitinol wires with the thicker set being radio opaque. The device is highly kink resistant and sufficiently flexible for use in vasculature with complex bends.
