Publication number: 20230012025Abstract: Example systems and methods of treatment are presented herein which generally involve expanding a bracing frame within a blood vessel between a clot and an aspiration catheter, aspirating the clot through a passageway of the bracing frame, and supporting the blood vessel by the bracing frame as negative pressure is created by the aspiration. The bracing frame can thereby reduce likelihood of blood vessel collapse compared to a similar procedure which does not include the bracing frame. The bracing frame can be removed from the blood vessel during treatment. In some examples, the bracing frame can further function to expand a mouth of the catheter. In some examples, the system can include a stentriever.Type: ApplicationFiled: July 12, 2021Publication date: January 12, 2023Applicant: Neuravi LimitedInventors: David VALE, Brendan CASEY, Karl KEATING, Ronald KELLY, Ray McCARTHY, Mahmood MIRZA, Sarah JOHNSON, Anushree DWIVEDI
