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.Type: GrantFiled: December 19, 2019Date of Patent: February 27, 2024Inventors: Sujesh Sreedharan, Anku Sreekumar, Sreehari Unnikrishnan Nair
