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

Publication number: 20200305900Abstract: A clot retrieval device for removing occlusive clot from a blood vessel. The device comprises an inner elongate body having a collapsed delivery configuration and an expanded deployed configuration. An outer elongate body is at least partially overlying the inner elongate body.

Patent number: 10682152Abstract: A rapid exchange (RX) catheter may provide a proximal seal against a guide catheter inner lumen so that aspiration may be applied through a guide catheter. The catheter may include an exit port that defines a transfer port for aspiration and may enable minimal frictional engagement with the guide catheter proximal of the exit port. Aspiration can be applied to the lumen of the guide catheter and may be directed to and effective at the tip of the RX aspiration catheter. A tip of the RX catheter may facilitate aspiration and retrieval of the clot by expanding under load and can also partially or fully occlude the vessel.Type: GrantFiled: May 18, 2016Date of Patent: June 16, 2020Assignee: NEURAVI LIMITEDInventors: David Vale, Brendan Casey, Michael Gilvarry, Kevin McArdle, Maeve Holian, David Hardiman, Alan Keane, Daniel King
