Patent number: 10792056Abstract: A catheter has an expansile tip that can be delivered in a constricted form. The increased tip diameter facilitates the aspiration and removal of large clot volumes by increasing the area of the catheter tip that applies aspiration to the clot. The tip comprises a support frame which can be cut from a metal or polymer tube, covered with a thin polymer sleeve 909 containing highly elastic properties. This construction provides good pushability and high compressive resistance. The cut pattern can contain axial connections of the support frame and ring members, which will provide a large level of axial support, lateral flexibility and hoop strength to withstand aspiration. The tip of the device can contain a section proximal of the highly flexible area that can expand to except clot. This potential to increase body diameter facilitates the retrieval of large volume clots while the construction of the catheter provides good column stiffness to avoid axial collapse and still maintain good flexibility.Type: GrantFiled: November 28, 2016Date of Patent: October 6, 2020Assignee: Neuravi LimitedInventors: David Vale, Brendan Casey, Michael Gilvarry, Kevin Mcardle, Maeve Holian, David Hardiman, Alan Keane, Daniel King, Jacqueline O'Gorman, Eamon Brady
